I don't need it, dying is really one of the easiest things for a human
our fragile bodies are very susceptible to pain and injury
if we flew into a window at a speed proportional to birds' body size/speed, we would die
yet birds always leave the scene in the same shape they left
That's because birds fly into things all the time, and they're pretty immune to it at this point because only the birds that would survive hitting stuff originally reproduced.
Natural selection, I believe it's called. It weeds out the weak and hence develops traits that aid in survival of the species.
Anyway, since you can die at any time basically, it's best to make the most of what you can do while you're alive. That's cool if you want to die to see what happens, but do what you can while you're alive, because I doubt much happens when you die.
