I fear it all the time. My greatest fear is withering away with ALS or a debilitating disease that requires someone to take care of me.
I read more and more stories of euthanasia and it candidly freaks me out. I could not imagine getting pumped with terminal sleeping pills with everyone staring at me while I expire.
The other day I was on my phone and I walked out into traffic thinking I had the right away. I got pulled back by a citizen; I would have been run over by a cab, definitely killed as there was a bus behind the cab. It was the grace of God and the instincts of fellow man why I am even here typing on this site.
