c'mon guys, where's your sense of fun? As the proud owner of a Y chromosome I do it as much justice as possible in a long series of stupid stunts.
Think about it, why are girls so sensible? they have two X-chromosomes that keep them from doing this kinda stupid stuff. Meanwhile, us blokes, only have one X-chromosome and also a Y chromosome, which is obviously the gene for stupidity. It makes perfect evolutionary sense, women take a lot longer in terms of their involvement in the reproductive cycle, meanwhile men can "do their bit" with little in the way to stop them from continuing (we dont get pregnant). To reduce the number of surplus males using up resources such as food etc, mother nature has helpfully included the Y-chromosome which makes us pretty stupid, especially when trying to show off to atract girls, so that we inadvertantly kill ourselves from time to time (if you don't believe me check out
the Darwin Awards and compare the male/female ratio)
This also accelerates survival of the fittest seeing as only the males who survive their own stupidity live to reproduce!!
So go out and do whats in your nature and perhaps use your personal right as a male and try to jump that ridiculous gap, try to climb that insanely tall tree/building and try out that "fireswing" idea that you had!!
**Disclaimer - don't listen to me too much, i'm having a bit of a rant here defending my choice to live life to the max, that doesn't mean that you should try jumping out of that multi storey carpark to imitate daredevil (believe me, that one DOES break backs). Oh and BTW don't use that for your biology coursework on evolution, its a sure fire way to an F-!!
