walking down the street, i saw a man who seemed to be homeless with wart-like bumps entirely covering his face. i've been researching, trying to find a picture of such a condition to share with you, but so far have had no luck. however, if you are feeling well, i found these lovely conditions (this last one is kinda what the guy's face looked like, except that there was absolutely NO clear skin ANYWHERE on his face). also in my searches, i came across this page of old time disease names.
