It would be best if you stopped shoveling snow at age 47. I heard that number on Coast-to-Coast one morning a couple of years ago. It was a weekend, and I was up early and listening to one of the show’s weekcited She was citing a study she had seen, where the authors picked 47 as an age when most people should stop shoveling. The number may seem arbitrary, and the report made it clear some people are heart-strong for much longer, and wouldn’t have any trouble.
