Please don't end it with a gun. Feeds the anti-gunner statistics. Seriously, we treat our pets better than our relatives. I don't want to end up like that dementia case but I would prefer a simple go to sleep not wake up death. I also don't want my relatives suffering any legal consequences for my passing.
John Denver went out doing the thing he loved. That'd be ok.
My dad tried sleeping pills..... didn't work. He was lucky he wasn't a vegetable when he woke up. I tried insulin... that didn't work either. But I was too cowardly to use a gun, and since I worked with LE for 40yrs, I know what a mess that makes for somebody else to clean up. I don't know what the answer is...
