Self Destruct

 I've been wondering if some humans end up being genetically programmed to self destruct.  I've known people who are suicidal and I knew someone who is gone from it.  I've thought about it.  I've noticed that there's two ways I think about it.  The first is if I'm really depressed and feeling sorry for myself because I've been mentally beating myself up. The second way is if I'm being almost coldly rational, like one might consider whether or not there's enough milk for a small or a large bowl of cereal.  It could be just a genetic lottery and be part of nature's way of avoiding overpopulation. I've never actually harmed myself.  Thought about it but haven't done anything about it. But I bet that people who succeed in killing themselves probably share a genetic marker, or at least a good proportion of them do. Someone ought to look into it.
