I get very little sleep. But I try to stay constantly busy. My fear is that if I stop working I'll, like, die. So throughout my life I've always tried to remain busy, and I sort of know no other way. I think if my heart rate slowed it would affect my constitution, strangely. I've been trained to do that.
If you just do a Google search and type in 'smoking' or 'lung cancer', you will be barraged with never ending facts and numbers, like how one in every three Americans is affected by lung disease and how COPD is the third leading cause of death and if you get lung cancer the odds are 95% that you will die.
I think I veered towards filmmaking because there's more of a sense of control in it. You're not waiting to be picked. That said, in film school I acted in probably 6,000 student films because no other filmmakers knew anyone who wanted to act. It was all a big beautiful snake eating its tail, progressing along the way.
