Thanks allforgood. I've actually been doing a lot of exercise in the past year or so. I've lost about 95lbs and gone from being obese to downright skinny, and I'm now in pretty good shape, I look good and feel great physically. I do an hour on the treadmill every day and also get in long city walks and mountain climbs when I can. It also helps to inform my emotional state of mind and keeps me out of the worst of the depressions, but it doesn't dig me out of the hole entirely, far from it.
