Could Extreme Exercise Help Slow Down the Aging Process?
from The Guardian
Every morning at 6 a.m., 72-year-old grandmother Dr. Betty Holsden-Smith enjoys the same exercise routine. She does a few crunches, lifts some weights, stretches and heads to the track to run — for 12 hours straight. Barely stopping to eat, drink or sleep, her longest "ultra-run" covered more than 100 miles and took three days and three nights to complete. Now this supergran from Maryland is hoping to double her personal best by running a six-day race in Arizona.
