Well I look at it like this: When you go to a restaurant the less you know about what happens in the kitchen the more you enjoy your meal. If the soup tastes good everything's cool and you don't necessarily want to know what's in it. The same thing holds true with movies.
It is my art. I am better at it than I ever was. And I will do it as long as I can. When you reach a certain age you can slough off what is unnecessary and concentrate on what is. And why not?
