The differing biological changes happening in the bodies of men and women as they age, the differences in longevity, how they age and their attitudes to aging are shown here by Clare Ansberry of the WSJ. This is relevant in the context of healthy living and also as both tackle the pandemic. There is a 5 year difference in longevity with men aging faster than women. Some groups of men have a tendency to eat less healthy and smoke than women in general which may account for some of the difference in longevity particularly in the U.S.

Men experience greater inflammation in the blood with aging, and lose anti-body producing B cells in the blood after the age of 65. Significant female advantages are seen in memory after age of 70. A look at protein level changes in blood showed more changes in men than women after age 65. Overall women's biology is seen by scientists as more stable than men's.

This excellent article by Peta Bee looks at how we can do anti-ageing efforts to keep our immune systems strong as we become older. She looks at work by an expert in immune cell biology, Janet Lord, who is head of the Institute for Inflammation and Ageing at Birmingham University. It is now proven that the link between ageing and immune systems can be guided in constructive ways. At sixty and seventy years age one can have the immune system of a 30 year old by doing a couple of simple things which are covered here from taking 10,000 steps a day, high intensity interval training on some days each month, occasional fasting on some days, high fibre diet and vitamin D. Walking, running or other forms of exercize affect a particular form of immune function called neutrophil movement in positive ways. Neutrophil movement because these cells are the main defense against the forms of bacteria that cause pneumonia. Neutrophils in older adults behaved in ways similar to that found in 30 year olds when doing 10,000 steps a day of exercize. Dr. Lord and other researchers have found. Dr. Jenna Macciochi, a lecturer in immunology at the University of Sussex, says about 70% of our immune system resides in our gut, making gut health very important for our immunity. Macciochi is the author of Immunity: The Science of Staying Well. Important for gut or gastrointestinal health is the eating of food that has prebiotic and probiotic effect. This helps reverse the decline of immunity coming with ageing.When we chew down on fibre in vegetables, fruit, beans or lentils we have beneficial byproducts called postbiotics that act as an interface between diet and immunity, that change the personalities of cells and circulate in our blood for regulation of immune system, says Dr. Macciochi. Postbiotics from eating dietary fibre tune up specific virus fighting cells that help us fight infections from flu and viruses, studies show says this report in The Times. Women in the UK get only 17g per day, men 20 mg per day of fibre. We need 30 mg per day of fibre and to do this we need to increase our intake of vegetables, fruits, whole grains, nuts, seeds and pulses. Also important is avoiding the inflammation that comes with ageing called inflammageing, says Dr. Macciochi. To do this do resistance training, weights, or using body weight such as lunges, push ups, squats. When our muscles move we produce hormones called myokines that help our immune cells function and keep inflammation down. She believes strength work is an absolute essential to rejuvenate our immune age. ...

Karishma Vaswani of the BBC points out that most of China's economic growth came with the shift to a market economy made by Deng Xiaoping in 1979, when he announced that China would follow a program of "socialism with Chinese characteristics." By comparison the 19th Party Congress is more about stabilization, preserving the gains made so far after Deng's opening up of the economy to foreign investment and technological collaboration. The placing of thought of Xi Jinping into the Chinese Constitution is more about setting a path of stable direction by the Communist Party than of major changes. The gains in the economy have come with some costs that will have to be addressed by an aging society. Particularly the problems of air and water pollution that other economies in Asia and Latin America following their own development paths would now strive to avoid. An anti-corruption drive was part of this effort for stable direction as the problems of debt to GDP ratio of close to 270% with an aging society remain to be tackled. There is still a large gap between the upper middle class and the rest of China as a result of the rapid growth. In this sense Jinping's effort at the 19th Party Congress is more about restoring the credibility of the Chinese Communist Party as China tackles the next stage of growth needed to catch up with Japan or South Korea. ...

The 3000 delegates at the annual China party Congress and premier Li Keqiang showed support for President Jinping as the Congress makes changes to the constitution. The constitution was amended to include a reference to Mr. Xi's political theory, that the Communist Party would lead the country as it implements socialism with Chinese characteristics, creating a new anti-corruption commission that has party oversight of all public servants. As Mr. Jinping, 64 years,  begins his second five year term, to ensure continuity and stability the clause in the constitution that limits a president to 2 five year terms was removed. Wang Chen is the Congress vice chairman and he led the anti-corruption campaign in China that firmed up popular support for Jinping in China. Wang Chen explained that the term limit changes were designed to bring presidential tenures more in line with Mr. Xi's other positions as Party chief and military commission chairman, positions with more power and no formal term limits.  The process is part of government restructuring that puts the Communist Party more in charge of decision-making.   There was some instability under the administration before Jinping and growing corruption had undermined confidence in the Party, just as China's economy was slowing, with a bubble in real estate, high debt to GDP and need to pursue a soft landing for the economy. The present effort say some delegates including the president of Haier Appliance, is an effort that stable economic policies can be pursued to ensure China's future as its society ages, and the need to complete modernization in parts of the country that have not seen the gains seen in the coastal regions. And that corruption does not undermine the party's credibility to lead this change. The huge economic problems China faces, bigger now from a public interest perspective of pensions, social security in the Chinese context for an aging society, bringing the rapid development of the coastal regions to the interior of the country, housing, the high debt to GDP ratio, and need to ensure good economic growth to provide a stable economic foundation, may have led to a sense that a stable political foundation was needed to ensure this takes place. Political stability was affected during the previous Hu Jintao administration with the Bo Xilai episode when the party unity was affected as "some  party cadres and leaders were giddy and feverish on the waves of the market economy" as Jinping put it at Central Party School in 2013. Mr. Jinping grew up amid such tensions as his father a senior party leader went out of favor first with Mao and then with Deng after the Tiananmen protests. This instability in the country that affected economic progress is part of the experience of older Chinese leaders and affected their perception of events from memories of this period. Some of the media coverage on this topic can be misleading, as it is important not to forget that China suffered for 2 centuries in the nineteenth and the twentieth century -with British invasion in the nineteenth century and Japanese invasion in the twenty first century followed by the chaos of the Cultural Revolution before finally finding a way out of poverty and backwardness in the final decade of the twentieth century and the first two decades of the twenty first century.  ...

Gerard Lemos writes from London about Chinese society today. He was visiting professor to Chongqing University of Business and Technology from 2006 to 2010. During this period he talked to many ordinary Chinese to find out what was on their minds -concerns that stemmed from China's one child policy, urban migration, health care needs, education and jobs were all uppermost in their minds. Lemos says even with the rapid industrial progress the lives of ordinary citizens are affected by fears and uncertainty about the future. The lack of jobs, lack of good healthcare, children who have migrated, are all part of their daily lives. For older people the one child policy in an aging society means the prospect of being alone in old age and the prospect of inadequate health care. For the young education and job concerns. Lemos points out that it is not about a choice between China's model and a Western model, it is more about a search for the Chinese soul, now that the basic material conditions are in place with the usual gaps and problems. At the same time it is a society prone to political sentiment such as the anti-Japanese protests....

The appointments to key economic positions in the Jinping-Keqiang administration in 2013 reflect continuity and importance given to experience. Zhou Xiaochuan continues as head of the central bank PBOC, to keep an experienced person in the the event of a financial crisis. Lou Jiwei, chairman of the sovereign wealth fund, is now the new finance minister. Xu Shaoshi, minister of land and resources, is the new head of the National Development and Reform Commission, the economic planning agency. Xiao Gang, chairman of the Bank of China, one of four state owned banks, will be the new head of the securities regulator, China Securities Regulatory Commission. Zhang Gaoli, a member of the Political Standing Committee of the Communist party, and Wang Yang, party chief of southern Guangdong province, also join the economic team. Li Keqiang, the new prime minister emphasized the agenda for the next decade telling a press conference: "Talking the talk is not as good as walking the walk. We need to pursue market oriented reforms." This means giving the private sector and consumers a signficant role in the Chinese economy....

China's July 2012 exports were up barely by 1%, over the same month prior year. Exports to the European Union declined by 16.2%. A big problem is cost increases for land, labor and electricity. By 2004 China's exports were growing at a peak rate of 35%. Since then prices of inputs have increased- wages by 150%, land by 70%, and electricity prices by 30%, according to Dragonomics. The yuan appreciated by 30%. Productivity is increasing by about 8% a year, according to the World Bank. As a result of the price increases of inputs the competitiveness of China, with products exported mainly on the basis of price, is deteriorating.

Efforts to boost the share of national income that goes to rural households and workers in China. The share of income taken by state owned enteprises and taxes paid by the enterprises would have to change for reducing the gap in incomes and reducing inequality in China.

"China's Superbank," by Henry Sanderson and Michael Forsythe looks at the rise of China Development Bank to provide insights into the two decade real estate boom in China, and the trillions of dollars in loans made by state owned banks to finance China's state owned industries and infrastructure development. The authors say these loans based on land owned by the state, improved with roads and other infrastructure and then sold to industry, have helped finance China's urbanization and industrial development. But it has also created problems including eviction of farmers from the land by local government authorites increasing inequality, led to misallocation of capital on bad projects, and an unsustainable model of development focussed on state owned companies. A major side effect of this is not covered in the book. This is the impact of crowding out of credit for private industry in China, with privately owned business having to pay higher rates in the underground loan market or lacking financing. A major focus of the report "China: 2030" by the World Bank and China's official think tank Development Research Center is on reversing this development to come up with a sustainable development model. The report was supported by World Bank chief Zoellick and China's new prime minister Li Keqiang. "The Great Rebalancing," by Pettis, a finance professor at Beijing University, looks at the other side of the financing of China's boom- the low interest rates on savings for China's consumer. This reduces household incomes and reduces purchasing power as the interest rates are lower than the rate of inflation. Lower value of China's currency also reduces the purchasing power for China's consumers. Estimates show the low interest rates cost China's workers and consumers somewhere in the range of 3 to 8% of GDP annually in bank deposit income. This money is funnelled through the banking system to make more loans for infrastructure and growth at the state owned companies, concentrating exraordinary level of financing in one direction. As a result the consumption share of GDP in China has actually fallen in the two decades of hyper development. This is about 34% compared to 50-55% for other Asian economies....

A recent book "The Spirit Level" has become popular in Britain. It says that countries with greater disparities in income also do worse in a number of social indicators, from higher murder rates to lower life expectancy. It also affects the consensus in society which is a necessary underpinning for sustained economic development and economic growth. Inequality when it affects the middle class and reduces the size of incomes in the middle, or creates stagnation in incomes, poses large risks for society and affects economic growth. In the US the home foreclosure crisis and the lack of bargaining power of wage earners in the middle class has created this problem. This is exacerbated by the banking crisis and bad loans in the banking system. Studies show that slow growth in college graduating rates in the USA after 1970 compared to the period 1900-1970, has increased inequality, especially with today's knowledge economy. Germany is also affected by this problem as wages for workers have remained stagnant with the labor reforms. Interestingly a combination of economic growth and payments to the poor have increased the size of the middle class and its incomes in Brazil. The austerity policies in Britain will affect incomes and income growth in Britain for the middle class. In China the gap is widening quickly between the urban areas and the rural areas. And the policy of residency permits- the hukou system-which limits internal mobility from rural areas to the cities and towns, makes the inequality all the more glaring. The lack of democratic election makes the situation worse in China compared to Brazil, because free elections in Brazil enabled leaders from the working classes such as Luiz Inacio Da Silva and Ms. Rousseff to emerge as heads of government. These leaders pursued policies that would explicitly bring a more shared prosperity in Brazil compared to the leadership in China. In China policies are determined by entrenched interests in its model of development- the state-owned companies and banks and their managers, local and government officials of the Communist party, and businesses with the networks and connections with the Communist party and local governments. This is why the ginni coefficient which measures inequality has dropped significantly in China, putting it in the rank of developing countries with poor records in equality. Inflation in China, India and Africa also affects the poor and lower middle classes to a greater extent. Current trends suggest that rebuilding the middle class in the developed countries and providing fairer distribution in developing countries will be of serious importance in coming years. Especially with the likelihood of more economic crises which tend to adversely affect the middle and lower classes disproportionately....

Martin Feldstein says China is gaining control of three problems it faces of shrinking export markets, the effects from a large stimulus in response to the 2008 financial crisis, and inflation especially high real estate prices. The economy is shifting to higher role for services and less dependence on exports under the new five year plan. The real estate prices are levelling off after steep increases. And inflation is under control. New investment will go into infrastucture needs such as power development and low income housing. As the economic problems are being tackled, the political problems remain. China faces an aging population under its one child policy, and it will have to support an increasing number of retired people in the future. Inequality and corruption are two problems that continue to grow and present challenges to the new leadership taking over in 2013.

Critics of the Obama administration's so-called "light footprint strategy" for the Middle East say it is more about keeping distance from problems in that region. This is a reaction to the extensive involvement of the U.S. in two wars in that region and intuitively makes sense, as well as being in line with American public opinion to focus on problems at home. The shift or pivot to Asia of president Obama also comes in that context. The problem with this approach is that this ignores the fact that most of the momentum and effort for the freedom struggles throughout the Middle East from Tunisia first, then Libya, Egypt, and now Syria, comes from within. The lead role is now being taken by France and Britain, with German public opinion also lined up in support. The U.S. in forfeiting its role as a facilitator with strategies such as "no-fly-zones" is losing the opportunity to gain the goodwill in the Middle East with cost that is negligible in comparison to the cost of Iraq and Afghanistan, and comes after the huge U.S. effort to remove one dictator in Iraq. A minor followup effort is all that is required from an administration that pushed for the "surge" in Afghanistan. When history is written the investment of the Obama administration in Afghanistan may show little results, if what is considered by the media and experts as an unpopular and undemocratic government of Karzai falls in the aftermath of the U.S. withdrawal. There is little doubt in public opinion in the U.S. and worldwide that the movement for freedom and democracy in the Middle East and democratically elected governments will become a lasting facet of the new Middle East. It also provides huge opportunties for trade and investment as is shown by the gains made by Turkey in just 2 years. This is why the Obama adminstration policies in the Middle East show a lack of grasp of the facts showing the Middle East as opportunity more than threat for the next decade, especially in its overreaction to the Bush era policies. This happens as there is a demographic explosion of young people in the Middle East. An administration that was keen to sense the demographic changes in North America, has failed to grasp this fact and why the struggle in the Middle East flashes daily on television screens young people carrying on the struggle. A pivot to Asia means a pivot to the Far East more than Asia because India is part of the South Asian-Middle Eastern region, which presents another paradox because as China is slowing the entire South Asian-Middle Eastern region of Asia is where future growth is expected to accelerate in the next decade. ...

Spain's central bank was lauded for macroprudential supervision before the housing bubble burst. Will China's central bank and financial authorites which have managed the housing bubble upto this point face similiar problems? Can China be the sole exception even as housing bubbles burst with wide repercussions in the U.S., UK and Spain? Nicholas Lardy, of the Peterson Institute of international Economics, says urban housing stock makes up 41% of Chinese household wealth in 2011. The same figure for the U.S. is 26%. Chinese buyers invest in homes because low interest rates on savings accounts cannot keep up with inflation. Real estate investment was 13% of GDP in 2011. Home ownership is a recent development in China, only since 1990, Chinese have never experienced large price declines. Household debt as a percentage of disposable income has increased significantly in recent years, up to 53.6% in 2011 from 31.3% in 2008, according to Lardy.

The Economist points out that China's total debt of government, corporate and households has grown by about 100% of GDP since 2008. The 2009 crisis led to rapid increase in debt. It is now about 250% of GDP, according to the Economist. Slower growth of below 7% risks reducing China's ability to service this debt. About half of this debt is owed by state owned companies and property developers. China can use its sovereign reserves to continue supporting bank and state owned companies. Investor's are pricing bank shares to reflect about 10% of this debt as bad debt even though government estimates are much lower. The reserves provided China time to fix the banking system since 2008, yet the debt keeps growing and China has failed to take strong action in the last 6 years. Complacency is a problem, and the incentives for local governments to continue prior practices that increase debt continue. As Krugman and other experts have pointed out at some point the rules of finance will apply to China as they have for other countries that faced a debt crisis- Japan in the late 1980's, South Korea and other Aisan countries in 1997, and the U.S. in 2008. Even without a crisis through deft managemen and use of reserves China risks zombifying the economy as old loans are backed up by new loans, with the further risk of misallocation of capital or poor use of capital. This lowers productivity of capital and hurts development. With poor statistics such as the figure of 1% of debt being bad debt cited here, the problems of complacency can be magnified, as there is less reason for a strong response....

A shift in priorities away from focussing on high growth to lower sustainable growth was announced by China's premier Wen Jiabao at the National People's Congress, China's parliament, in March 2012. This shift will reduce investment in infrastructure, power generation and exports, which will affect the level of imports of commodities from commodity producing nations in the Middle East, Australia, Canada and Brazil. It should increase imports of software, computers, entertainment, tourism and high tech goods from the U.S. and Europe. Chinese leaders have said they would make this kind of shift for some years now but growth has consistently increased more than the target rate, and domestic consumption as a percentage of the economy has actually decreased in the last decade. Now 9-10% growth rates may be a thing of the past and the target of 7.5% set this year may be actually closer to the real figure. The Chinese leaders have belatedly realized the need to make these changes now because slowing markets in Europe -which is seeing declining growth and high unemployment- and in the U.S., make the issue impossible to avoid. Wen told the Congress: "Accelerating the transformation of the pattern of economc development... is both a long term task and our most pressing task at present... Domestically it has become more urgent but also more difficult... to alleviate the problem of unbalanced, uncoordinated and unsustainable development." This is his way of saying that its unavoidable and better to start in earnest now, and at the same time recognizing the resistance to change from the stateowned companies and the other interests who have benefitted from surging growth, and now occupy a central role in the power structure. An opinion article in the People's Daily, China's official newspaper, said: "imperfect reforms are to be preferred to a crisis caused by no reforms." The World Bank's president Zoellick is respected by the Chinese leaders. He also urged them to make changes now. The recent report of the DRC, China's planning research arm, and the World Bank, also laid out the new direction away from a focus on infrastructure to domestic consumption. The fear is sudden deceleration in the absence of policy action. The impact of this will be negative for commodities over time, leading to slower growth in Australia, Brazil, and Canada. It should boost imports from Europe and the U.S. of high tech, consumer, pharmaceutical goods over time....
