So far everyone that has told me they were gonna do it .....didn't.....(has happened more times than most would suspect)
when it comes to terminal illness I am on the fence as I would never let an animal suffer the way some seem to feel a human should 
so far in my family everyone dies surrounded by family, we may suck ass at weddings and marriage but we rally when it comes to death and dying
So far everyone I have heard say that they would have not done it.
The people I have known that did do it did it unexpectedly
It's almost like when you have two guys yelling and talking crap, they usually do not end up throwing blows. It usually is a guy that says nothing and just walks up and throws a punch
Always pay attention to the guy that keeps a eye on you but will avoid eye contact
