I had totally planned on smoking pot when my mind started to go from age because at that point, who cares? Plus, i loved Michael Caine's elderly hippie pothead character in Children of Men. But this is fantastic news.

Researchers led by Andreas Zimmer of the University of Bonn in Germany gave low doses of delta 9-tetrahydrocannabinol, or THC, marijuana's main active ingredient, to young, mature and aged mice. As expected, young mice treated with THC performed slightly worse on behavioral tests of memory and learning. For example, after THC young mice took longer to learn where a safe platform was hidden in a water maze, and they had a harder time recognizing another mouse to which they had previously been exposed. Without the drug, mature and aged mice performed worse on the tests than young ones did. But after receiving THC the elderly animals' performances improved to the point that they resembled those of young, untreated mice. "The effects were very robust, very profound," Zimmer says.

I might actually start remembering characters' names in movies again!

Other experts praised the study but cautioned against extrapolating the findings to humans. "This well-designed set of experiments shows that chronic THC pretreatment appears to restore a significant level of diminished cognitive performance in older mice, while corroborating the opposite effect among young mice," Susan Weiss, director of the Division of Extramural Research at the National Institute on Drug Abuse who was not involved in the study, wrote in an e-mail. Nevertheless, she added, "While it would be tempting to presume the relevance of these findings [extends] to aging humans...further research will be critically needed."

Pshaw...i've got all the info i need. By the time i start, my brain will already be going, so there's nothing to lose. Either it makes my brain better or i won't know to care.
