The late Richard Feynman, a superb physicist, said once as we talked about the laser that the way to tell a great idea is that, when people hear it, they say, 'Gee, I could have thought of that.'

We can't avoid age. However, we can avoid some aging. Continue to do things. Be active. Life is fantastic in the way it adjusts to demands; if you use your muscles and mind, they stay there much longer.

At least this is the way I see it. I am a physicist. I also consider myself a Christian. As I try to understand the nature of our universe in these two modes of thinking, I see many commonalities and crossovers between science and religion.
