Sept, 2010, so it's possible you've seen it before: http://blogs.scientificamerican.com/bering-in-mind/2010/09/22/an-ode-to-the-many-evolved-virtues-of-human-semen/ An ode to the many evolved virtues of human semen "Perhaps the most striking of these compounds is the bundle of mood-enhancing chemicals in semen." "Such anxiolytic chemicals include, but are by no means limited to, cortisol (known to increase affection), estrone (which elevates mood), prolactin (a natural antidepressant), oxytocin (also elevates mood), thyrotropin-releasing hormone (another antidepressant), melatonin (a sleep-inducing agent) and even serotonin (perhaps the most well-known antidepressant neurotransmitter)." " women having unprotected sex should be less depressed than suitable control participants." ----- If you haven't seen it, the snowboarding crow is pretty darn interesting: http://blogs.scientificamerican.com/video-of-the-week/2012/01/18/snowboarding-crow/ -- You received this message because you are subscribed to the Google Groups "Web-Heads" group.
