It's not that you "don't have the balls to jump" we're not talking about stunts here or jumping into a big river. If you think "ehh I can't do it." It's probably because you have the will to live. Which isn't being afraid. It's literally more frightening to go on living until old age then it is to just go into nothingness. You could end up homeless or any other number of terrible scary things in life. Death is scary sure but only if you don't want to die. If you do it wouldn't be that scary.
