Hahaha great. You've said it all lol. For me, I just wanted a better condition that allowed me work and cater for the family, unfortunately I didn't get it. I have many people with my conditions who wished they weren't born, I get the pain and frustration, sometimes the pain of life begins to exceed any happiness we derive from living it.
100 years is a really long time, I think 90% of people don't have that much of good genetics that lets them live into 100.
However, we are who we are, and we cannot change it as tigve pointed out.
