Pumping Iron at 90

If you doubt the benefits of resistance training as you age, just ask Ben Sann. He's 90, and still lifting, according to today's New York Times.

Working out gave him a "whole new life," he tells the newspaper, and helped him fight the depression that descended upon him after his wife died. Oh, and when shoppers push him in the always-crowded Fairway supermarket in Manhattan, he has the strength to push back. (I shop there, too, and there's plenty of pushing, unfortunately.) He aims to do better every workout.

"He is determined to be the oldest man on the planet," his son tells the Times.
