Debbie Downer thought of the day

Evolution needed to reward us immensely for eating and fucking, but perhaps it also punishes those who think too much about evolution by making them feel depressed when they realize they can view the raison d'être of all lifeforms as just wanting to exist as long as possible and also make copies of themselves. So if we're bummed by that thought, we'll stop thinking about it because it sucks and go back to sex and chocolate.
