Keeping Young

Tony and I ran the trail today for about 8 miles at a relatively easy pace . The last three quarters of the mile was run at a pace about a minute slower than Tony's best. My friend Wayne Fiske sent me an article titled "Can Exercise Keep You Young" featured in the New York Times on March 3 ridden by Gretchen Reynolds . The article  is about research  conducted  by Dr. Mark Tarnapolsky. In his study, Dr. Mark compared mice that had been genetically programmed to grow old at an accelerated pace . In his study, a group of mice were on a wheel and ran for 45 minutes three times a week. The exercised for five months. The control group were mice that didn't exercise. Findings suggest that the group that exercised either reduced or eliminated  the effect of  aging on the variable studied  . Tony told me "I could have told them that-they didn't have to do the study with mice .

An article that appeared in the Wall Street Journal on February 22, 2011, written by Ann Lukits is titled "Exercise Boost Brainpower ."In this article a year of modest aerobic exercise reversed normal brain shrinkage in older adults by one to two years and improved their memory function. The study appeared in the Proceedings of the National Academy of Sciences. As people age, the hippo campus the brain's memory center loses one to 2% of the volume annually affecting memory and possibly increasing the risk of dementia. One group in their late 50s to early 80s walked three times a week for 40 minutes aiming for their target heart rate while the other half did yoga and toning exercises. The hippo campus in the walkers increased by 2% after year and shrank by 1.4% and the controls.

In addition to reading my book, you'll have to exercise in order to take advantage of these findings. My book and my prescription is going to allow you to reach benefits unheard of.
