Sex Boosts Brain Growth
climenole writes "Sex apparently can help the brain grow, according to new findings in rats. Sexually active rodents also seemed less anxious than virgins, Princeton scientists discovered. Past findings had shown that stressful, unpleasant events could stifle brain cell growth in adults. To see if pleasant albeit stressful experiences could have the opposite effect, researchers studied the effects of sex in rats."
The major goal in any living being's life is to ensure the survival of his genes.
Nothing personal, but no.
It is true that natural selection requires you to compete successfully in order to continue to exist, and that includes reproduction. But, natural selection is not the only principle governing nature, it is merely a very important one. A lot of behavior is effectively orthogonal to survival: you can do something, or not it, and your survival chances are the same. Furthermore, life is not entirely a zero sum game. Certain things, like cultivation of intelligence increase your chances of survival to the point where you have freedom for a lot more besides that. You can say that its instinct for propagation of genes that compels us to learn. And there's truth in that. But satisfying the instinct is just one condition that has to be met. Its not everything.
You're free to pick any 'major goal' in life that you find compelling. Of course, if your goal isn't conducive to the survival of your bloodline, then nature will kill you off. But that doesn't mean its impossible to make that choice.
If more nerds got some, maybe we'd have the Higgs Boson on lock already.
Historically, how common is it for scientists to get serious work done when they're in love or chasing hot women? The degree of concentration and dedication required for groundbreaking work would seem to me to usually preclude that. Sure, lots of famous scientists fooled around or had lots of kids. But I have a hard time believing very many of them were doing their best work in those periods, or that it occupied a very high part of their attention.
There may be other aspects of sex affecting the brain also.
Some believe that hormones transmitting during some sex relieve depression.
According to Neal Stephenson in Cryptonomicon, masturbation is effective, but does not last as long, so you have to do it far more regularly. I would have to reread it to see if he says if it's as effective as the real thing though.
Now from personal experience, something most slashdotters don't have, I would say the real thing is both more effective and has a longer duration.
