Yes, but sleeping is also a natural function...oh, bugger it. I'm not going to convince you to do the sensible thing and load yourself full of drugs before undertaking such a long journey no matter what I say, am I?
Talking of which, I watched Vanishing Point for the first time the other day. Now that's a ****ing odd movie.
Oh, yes. It wasn't good, but it was sort of fascinating. Very much of its time. Speed freak tries to drive across much of the United States after a bet with his dealer and encounters various hippies and rednecks. Weirdly nihilistic and had Petrocelli and the Sheriff out of Blazing Saddles as a blind DJ. **** knows what the point of it was.
