This is so strange. I have had about ten of my friends standing in front of me doing all sorts of wierd poses, and none of them could raise their arms more than about 15 degrees above shoulder level while their arms were straight and palms pointing down, but in the first ten minutes here are two people who can do this. Odd. I can do it as well, and no one would ever mistake me for being limber. I'd suggest that if they can't raise there arms higher than that, they have problems. I don't see how someone couldn't do it unless they had no turning ability in their wrists.
