    Arrow "Slowing aging with semen"

    I'm not making this shit up.
    Well, it makes sense in terms of sexual competition, especially in non monogamous species to have ways to keep the semen alive longer while remaining mobile/fast to get the best ratio of survivors at 'the end of the road' and therefore more fecundity. While there's no incentive (well, more with a slow growing cultural social species such as humans but still relatively few) to hold aging in a population (in terms of natural selection).

    So, yeah.


    Hold your laughter. It's not the setup for a joke. Austrian researchers believe that a compound in human semen can have a dramatic impact on life span. Biochemists Frank Madeo and Tobias Eisenberg at the University of Graz led a team to test the effects of a substance known as spermidine. In yeast, spermidine was shown to increase life span by as much as a factor of four; in fruit flies, up to 30%; and in worms, up to 15%. When spermidine was applied to human immune cells, they too lived longer, with three times as many surviving after 12 days as in a comparison batch.

    Spermidine works, the researchers show, by promoting the cellular process of autophagy — a kind of self-cleaning that, Eisenberg says, "removes cellular garbage such as clumped proteins or damaged or defective cellular organelles." Those things might otherwise harm the body.

    Do you rub the semen into your face or something? Sort of like a cleasning mask I suppose.

    This will not end well...
    But it will at least be poetic, I suppose...

    Hmm... But what if it does end well?
    Then I suppose it will be a different sort of poetry, a preferable sort...
    A sort I could become accustomed to...

    ^Maybe you're supposed to drin - nevermind

    Of course they would isolate the compound prior to putting it on the mass market for human consumption, although you men could use this little nugget of gold to your advantage :P

    Oh, they'd probably find a way to produce it in recombinant bacteria or yeast or something. Don't get anyone's hopes up.

    And, the effect seems to decrease with more complex organisms, so it may have to significant effect on humans at all. Slowing aging in a human being is a different matter from increasing the life span of a cell.

    It's kind of funny that this "comes" from Arnold Schwarzenegger's hometown of Graz, Austria.

    Hey, this is why women statistically live longer.

    Why do I picture a scientist trying to convince his girlfriend to do certain things?

    It's a satisfying to me as coming is...

    I remember reading about this bodybuilder that was worried about losing the little protein in semen. Funny.
