I think about death a lot. Every time I see my 84 year old mom and 89 year old dad, I wonder if I'll ever see them again. When I see one of my cats lying very still I look closely to see if they're sleeping or dead. In the middle of the night I sometimes put my hand on my husband to make sure he's still breathing. I should probably stop that, it's kind of negative...
I don't think about my own death nearly as much, I'm not going to be hurt by it the way I will be hurt by losing a loved one.
What if you take your last breath, and your heart beats its last beat... but you die so quickly (in a car crash or being shot or something) that you aren't aware that it's the end? Would you feel cheated?
