I am much less autistic now, compared to when I was young. I remember some behaviors like picking carpet fuzz and watching spinning plates for hours. I didn't want to be touched. I couldn't shut out background noise. I didn't talk until I was about 4 years old. I screamed. I hummed. But as I grew up, I improved.

I feel very strongly, we've got to give animals a good life. I've worked really hard improving slaughter plants and animal handling and transport. And people have said to me, why don't you work on improving conditions on pig farms? And basically, to be effective on making real change out there on the ground, you can only work on so many things. You know, you get too distributed, you're not effective.

One of the things I want to do is be a decent role model. I've got a lot of emails and stuff from children. They look up to me. Kids get different labels and things like that and I want those kids to succeed.

If you have a 2-year-old who is non-verbal, don't wait until you get a diagnosis at 4. The child needs one-on-one teaching with an effective teacher now. This can be a grandmother or a teacher or someone from the community. Grandmothers are especially great. There are a lot of grannies around. Go to your church for help.

I was nonverbal until I was four years old. Back in the 50s, I was the kind of kid they used to just put away in an institution. But then you get the milder autism where there's no speech delay, but they're socially awkward. Those kids were around when I was a child. They were just called geeks and nerds.

If you start using a medication in a person with autism, you should see an obvious improvement in behavior in a short period of time. If you do not see an obvious improvement, they probably should not be taking the stuff. It is that simple.

I can explain how a person with autism thinks. I am very, very interested in how people think. It's been a gradual process of learning more and more about how my thinking process is different. You know it's bottom up - you take specific examples to make concepts and then I put them in categories.
