Most of the commited won't go for a way to kill themselves that involves suffering for more than five minutes, and if they try slitting their wrists, most of the time they regret it about 2 minutes into the process. If they really wanted to die, they'd buy a gun, or chop their hand off with something big.

Veins aren't the best way to extract blood, anyway, and that's why there are so many failed suicides each year.
I think people should just stop trying to kill themselves. It doesn't really do any good for anyone. If worse comes to worse and you can't kill yourself, think if it this way; maybe you're not supposed to die. Maybe you've actually got a purpose. So, stop being selfish and learn karate or something so people won't kick your ass so much.
