I Have Agoraphobia. I Don't Travel. I'm Not Able to Travel.

I have used the telephone to teach all over the world in Sweden, in Japan, South America, Australia. My brother built a one-two radio which never worked. I think the most important thing we can work on in communication is to make the world safer for the people who live in it. That's what I teach a course for NYU. I also teach media and public health at Harvard. Both places come here. I have agoraphobia. I'm not able to travel.
