Hooray, I must be a freak! 15 years ago I weighed 50 pounds more than I do today. 15 years ago I managed a 12 mile bike ride by the end of the summer -- I've finished a couple of 200k brevets so far this year.
Physical ability declines with age, but for people who remain physically active, it doesn't decline very fast.
