I go to an old folk's home every one or two weeks and see and hear about the physical woes the elderly live with. One woe makes it so that another woe won't improve, etc. It's very sad and sort of scary to me. I'd like to avoid as much of that difficulty in my later years as I can.
I get so darn little exercise where I work, basically sitting in a chair most of the day, sometimes standing in place part of the day. I get out in the boonies very little in the last couple of years due to work and family commitments so I haven't been hiking or shooting or fishing much at all.
So, I'm trying to stay in shape regardless. Non-bulbous shape, anyway.
I'm 6'1" x 187 pounds buck naked; 34x36 butt covers.
I do calisthenics every morning religiously and have for a decades (pushups, situps, bend and reach, etc.) That helps a ton. On weekends I get out and rollerblade on the pavement which is an excellent workout, and do yard work in the summer and shovel literally tons of snow in the winter, but that's about it.
I try not to eat crap food. I stay away from pig and potatos and don't allow margarine in the house; never ever drink soda pop and only rarely eat any kind of sugary stuff (I do have a thing for extra dark chocolate and extra dark beer though).
I know it's a battle we all lose eventually, but I'm going to try and keep the medical bills to a minimum as long as I can. Like I said, it's sad at the old folk's home.
