Sorry to hear about that, Boo.
I lost my father years ago to the same type of thing...lots of years of clean heathy living (a bottle of Jack Daniels and a carton of Camels.) Eventually he ended up with Alzheimers and kinda wasted away.
Now my 30 years of hard living is catching up to me. 3 (maybe 4) heart attacks and quadruple bypass 2 months ago...I may live for another 15 or 20 years, but I sure won't have the physical abilities I did when I was younger.
Btw, I gave up the booze 13 years ago and the cigarettes 11 years ago. But the effects are still with me. When I had the bypass surgery, just about every doctor who came to see me waggled his fingers at me and demanded that I quit smoking. I'd try to tell 'em that I hadn't had a single smoke for over 11 years, but they weren't buyin it. I finally figgered out what it was. The black paint that I used on my ol' Ugly Truck had worked its way into my lungs in spite of the masks I wore. Once I coughed all that up, all was well again.
So...a word to the young bolters from an old one (my medical records stated that I'm a 66 year old male who looks mildly older than my stated age...I'm actually 57...but I could pass for 70 pretty easy.) Anyway, the hard livin takes its toll, particularly the smokes. If you can handle the booze...fine. If it's causin ya trouble...well maybe it's time to consider givin it up so that you can keep the Stovebolts alive for many more years.
