Dunno about the reversed knee joints, though...
- This, from a letter in TOUCHSTONE magazine:
"...an article that Scientific American ran in its March 2001 issue ...
showed the results of an effort by three specialists on aging to redesign
the human body for endurance rather than beauty.
" The results are portrayed in an artist's ... conception ... our redesigned
human ... complete with large, pointed ears for better hearing, reversed
knee joints, shorter limbs, and a backward curving neck, needs only fur on
the top of its feet to pass easily as a Hobbit."
