Somehow I got a little out of shape over the past few years. I bought one of those devices that runs a current through your body and can tell exactly what you are made of. It can then tell you how old your body is in relation to the average.  On my last birthday I turned 50. According to the device, I am 76!

Thirty pounds ago, I got a Black Belt in karate and was seriously into mountain biking. When I went to buy a new mountain bike last summer, the sales guy asked me if I wanted him to mount a defibrillator on the handle bars.

How does a middle-aged person begin to get back into shape?
