I've been in elementary education for years and my belief is that Christmas pageants in schools are little more than conditioning kids for the Christian religion.
All the sudden high-impact stress can really take a toll on your body. So if you still want to be active and get in a good workout go to a yoga class or pilates class or get in some strength and conditioning.
I gained direct knowledge of the life of the poor in big towns: I have lived the narrowing mechanism of its conditioning and feared it.
There is no way to be truly great in this world. We are all impaled on the crook of conditioning.
When I grew up there wasn't air-conditioning or anything of that nature and this old car had a wall thickness of about ten inches. So we had a little warmer house in the winter and a little cooler in the summer.
Having played many roles of scientific intellect I do have an empathy for that world. It's been hard on me because flying the Enterprise for seven years in Star Trek and sitting in Cerebro in X-men has led people to believe that I know what I'm talking about. But I'm still trying to work out how to operate the air conditioning unit on my car.
