I don’t get much exercise. By that, I mean I don’t participate in any regular, repetitive actions where the primary purpose is to move muscles and blood. My physical activity tends to come from whatever project has caught my attention, whether from necessity or for amusement, usually the latter. Being the kind of obsessive personality I am, I tend to go at things all or nothing, so when I’m active, I tend to be very active. Of course, when I’m not active, I sit a lot. So, I figure if I physically work hard two months and sit around the next two months, I’m doing all right on average. Right?
