[Paleopsych] Kenan Malik: Is this the future we really want? Different drugs for different races

Sat Jul 23 21:43:42 UTC 2005

There are clearly age differences. As we age, the gut is less able to 
absorb, yet the liver clears things more slowly, so giving psychotropic 
drugs to the elderly is a real guessing game.

Sex differences have been ignored, much to the detriment of women. The 
fiction was that men and women are of the same species. Obviously an error.
