One area of study that still needs to be done is the kind of autism where kids have speech and they lose it. Some parents say it's happened right after vaccines. That group needs to be studied separately from others.

The squeeze machine is not going to cure anybody, but it may help them relax; and a relaxed person will usually have better behavior.

These diagnostic profiles like depression, ADHD, autism, dyslexia, it's half science and the other half is a committee of doctors bickering over what it should be, and it has changed. It's not precise like a diagnosis of tuberculosis would be very precise.

I think it's a real shame so many schools have taken out the hands-on classes. Art, music, auto mechanics, cooking, sewing, these are all things that can turn into jobs. You know, wood shop, steel shop, welding. These are all things that can turn into great careers, get kids interested. Things they can do with other students. Other things for our word thinkers: journalism clubs, drama clubs.

I think using animals for food is an ethical thing to do, but we've got to do it right. We've got to give those animals a decent life, and we've got to give them a painless death. We owe the animal respect.

I think the mild Aspergers have always been there. You see, Asperger's diagnosis did not become common in the U.S. until the early '90s. And an Aspergers has more or less normal speech development and they've always been here, that hasn't changed. I can think back to when I was in high school, this is 40 years ago, I could name kids in my high school class and college class that, today, would be diagnosed as Aspergers.

When I was younger I was looking for this magic meaning of life. It's very simple now. Making the lives of others better, doing something of lasting value. That's the meaning of life, it's that simple.
