1. Living a long, lonely life and dying alone. The sort of old geezer who is found out three months after his passing as nobody has paid my bills and there is an odour something foul reeking into other apartments.
1½. Ending up as one of those senile old folks who are slowly dying of several different maladies, losing their identity as their mind deteriorates, and are unable to perform such basic functions as going to the bathroom by themselves.
2. Failure. I got the heart of a goblin, really. The moment there's even one major setback, I'm throwing down my arms, raising up my own arms and run away screaming and flailing said arms, completely routed.
3. Losing my sight. I fancy myself as an artist, and most of the small sources of happiness I find in life would be denied from me if I were to turn blind.
4. Drowning. I like water, but the thought of traversing any frozen over bodies of it is a thought that doesn't sit well with my lunch. I see myself suddenly going under, into the cold dark depths, and never coming back up.
