Mysteries simply are a feast for an active mind. And while in my lifetime I've seen science make extraordinary inroads into solving the most complex questions of life, after all this time I admit that I am thrilled that there are some things that forever will remain a mystery. For example, do I wear a toupee?

I have been accused of never saying no.

My life is my statement and I try to be true to myself and thusly to other people. Whatever my failings are, they are human and I try to perfect it each day.

I want to discover a truth for myself that is really true. Whether it's a piece of scientific knowledge, or a philosophical truth.

I often conduct interviews in my truck.

I'm anxious to make another film.

A tree you pass by every day is just a tree. If you are to closely examine what a tree has and the life a tree has, even the smallest thing can withstand a curiosity, and you can examine whole worlds.
