I've read about something called the "Marburg variant" of MS that apparently works it's way quickly thru a person, but it's supposed to be extremely rare.

I wondered if Richard Pryor was one of those that was unlucky to have the Marburg variant, since it seemed like he went downhill fairly quickly after he announced his MS (or I'm just thinking it went quickly for him because he didnt do much entertainment-wise fairly soon after he announced it)

Richard Pryor was one of my most favorite actor/comedians when I was growing up. (yes, my parents let me and my sister listen to some of his more...risque comedy concerts when we were little) Loved all his movies that he did with Gene Wilder...I wish I didnt have MS in common with him tho...I wish that he hadnt had it either now that I know what it's like. (I wish no one had MS. It would be nice if "MS" only stood for "Microsoft")
