Puke : Interestingly enough, many Brazilian tribes practiced cannibalism, before the Portuguese arrived and Banned it. Which gives rise to one of my pet phrases : "Yes, tradition and cultural roots are a wonderful thing, let's revive the customs of our ancestors and go eat all the foreigners."
Puke again : that's the reason why fiction and games exist (or at least my opinion of it), but of course they have gone on to be much more.
Loser :
There were wargames before HG Wells (although he may have invented the commercial wargame), but the irony is still there. As is the fact that Monopoly was invented by a socialist who wanted to portray the evils of capitalism.
Narf : self-control goes so much against all our species survival instincts that it is almost a form of violence against oneself. So-called 'safe sex', on the other hand, does not really solve the problem either because there is a part of us that wants children, not just sex. It's interesting to see what society has come up with to appease the parental instinct in an overcrowded world : pets, consumerism, concentration of the population in cities where living space is scarce and the growing perception that sex is an end in itself. Wait, I remember a book that described a society like that, it was called 'Brave New World'.
