Aging does not happen gradually but happens in waves at early 40's and early 60's and at 78 years, say Stanford scientists. This means we should be proactive and act by having a regimen of exercises that we take extra care to do when we are at these ages so that we compensate for rapid muscle loss or other aging related issues including balance, posture, skin health, cardiovascular, and other health issues. Nutrition can also be geared to specific foods that will strengthen us.
