I find this thread very interesting so I just feel like I should say something.

I believe that as actors it is normal to experience performance anxiety, like a specific work situation or stage anxiety, something of that sort. I dont see them having (i want to say normal) social anxiety where as everyday dealings with people on an interpersonal level are difficult. (I heard something about jim carry, hes a nut case you can tell, hell even I can tell)
Now I have heard of some famous athletes that have a hard time with everyday social situations. Chris Kaman an NBA player i believe on the LA clippers right now and also Ricky Williams of the NFL.
(sorry if I regurgitated what might have been already said)
What do you guys think with my view?? anything/anyone to add??
