At least you sound like you’ve got the exercise part of it covered with the house/yard work. That’ll peel away the tension. That was part of Dad’s problem. He spent most of his time at the station and never did much in the way of exercise - the yard work was left to me and Mom. A poor diet and two packs of Kool Filter Kings a day didn’t help, either.
Ah, yeah. I also have an elliptical machine and a Total Gym that I hit, soooo... :-D
