The Hardest Part of Makeup?

The hardest thing i've ever done was probably when i played the mother bug in a movie called bug buster. How do you sit through hours of make up without going crazy? I'm not one of those people who hase to be doing something all the time. That works well in a make up chair. The real, the real test for me is when now i have to go to the set and perform and ave become alive while wearing something that is hot and heavy and sticky and cumbersome.
