Dr. Morris White, a Howard Hughes Medical Institute investigator at Children’s Hospital in Boston led a group of researchers who discovered in rat studies that the lower the level of insulin that reaches the brain, the longer the rats lived. One of the surest ways to do this is through regular exercise and dietary reform (I love that term). If we eat right and exercise we can live longer. Imagine that. Here is the Reuters story about the study.

What is interesting is that even people who don’t exercise now, they can get the benefits of lower insulin and perhaps a longer and healthier life if they start right away. Change your diet, stop eating junk food and lots of sugar. It will take work but you’ll be happier and feel better. It just takes that one step to get going.
