Some of the chickens, as they say, are coming home to roost that's for sure. When we're young we think we are invincible. I did some incredibly difficult and dumb things in my youth. Not that I have many regrets, but I can tell you when you get a bit older your body will remind you how stupid you were back when you were invincible. It could be worse and is for a lot of people. For a guy my age I'm in good shape and still regularly outwork men less than half my age. Nevertheless, a small ( by my standards) amount of work around the homestead on my day off yesterday resulted in me waking up with aching elbows, knees, neck and lower back. I'm sure by noon all will be well, then we can start the process all over again for tomorrow. That's the way it goes.
If you saw me shuffle out of bed at 4:30 AM, goaded by my cats who want breakfast and a desire for a cup of coffee, you might think I was a 70 year old man. By the time I get to work at 6 and that cup of coffee is gone I am once again superman.
