Here is a very good reason why we should take the best care possible of our digestive tract - it may hold the key to our longevity.
http://www.sciencedaily.com/releases/20 ... 093945.htm"By activating this one gene in this one tissue -- the intestine -- the fly lives longer; we slow aging of the intestine, and that has a positive effect on the whole animal," said Walker, a member of UCLA's Molecular Biology Institute. "Our study shows that increasing PGC-1 gene activity in the intestine can slow aging, both at the cellular level and at the level of the whole animal."
The biologists delayed the aging of the flies' intestines and extended their lives by as much as 50 percent.
