Even at almost 64 years old, I briskly walk or jog 2-6 mile each and every day, weather permitting (I live in San Diego, so the weather usually cooperates); I'm a very active member of the Hash House Harriers, a worldwide beer-drinking club with a running problem (see the links at
www.sdh3.com) wherein we do the hare/hound chases. It's fun, naughty, and good for one's health.
