Wouldn’t it be fantastically wonderful if the game of chess could be turned into rigorous physical exercise?
I realize now that you could do this with a multitude of otherwise sedentary pastimes–knitting, reading, watching a movie, etc., etc. Just make them hideously hard! Knit with thick rubber tubing instead of yarn. Hop around on one foot while reading from a book attached to a large concrete block. You gert the idea.
One drawback, though–
Imagine if you wind up with a Worse You instead of a Better You.
