Never too late to work out
From a Wall Street Journal story (subscription required) on investing in one's fitness:
Age is certainly no excuse. It turns out that 50-year-olds can win back the aerobic capacity they had in their 20s with six months of exercise, a new study has found. Even in your 70s and 80s, "you can gain muscle," says Carol Krucoff, a yoga instructor and author in Chapel Hill, N.C. "And every pound of muscle you gain raises your metabolic rate by 30 to 50 calories a day."
