Cats are great with clicker training. There's a great video you can get called "Clicker Magic". There's a scene in that video where a cat is trained to go through a mini dog agility course - it's all done with food motivation and clicker training. You can train them to do all sorts of thing.

For example, if ears are back on a horse, it's obviously not very happy. And the eyes show that it's not happy. Now, if the eyes are nice and soft and brown, then it's calm. You can see these things in horses and cattle, and I think that some of these people are just really good at picking up these signals, but they don't realize it.

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.

I can remember the frustration of not being able to talk. I knew what I wanted to say, but I could not get the words out, so I would just scream.

One of the places where research is needed is all the sensory problems. And you get sensory problems not just with autism, but with dyslexia, learning problems, ADHD, attention deficit, you know, things like sound sensitivity, problems with fluorescent lighting.

I believe there is a reason such as autism, severe manic-depression, and schizophrenia remain in our gene pool even though there is much suffering as a result.

Engineering is easy - it's the people problems that are hard.
