Working with Danny Thomas was truly an adventure every week. Danny didn't always say the words as they appeared in the script. I learned more by osmosis than by sitting down together. He was a force to be reckoned with: an explorer of television.

Lost in Space brings back a lot of memories for people, and I think that any time you're involved in something that has such a long-lasting appeal, you feel very blessed by that.

I think here in America the space programme was such an enticing thing to be going on, that the thought of a family being able to go into space and live up there was really kind of mind-bending at the time.

People think it must be wonderful being in movies or on television, but it can be very tough on a child. I had two friends in elementary school. That was it. There was a clique of girls that were brutal to me. They pulled some very mean stuff. My two friends got me through it. Without them, I would have been all alone.

I'm not totally altruistic. I've always had great career ambitions. But it has to come out in an organic way. If you push yourself out beyond where you are supposed to be, there's this pressure.

I did interviews with tennis greats, like James Blake and John Isner. I also interviewed tennis pros who aren't well - known but who made all the same sacrifices but had just a little spark of a professional career and are now still orbiting the sport, either as a teaching pro or a coach.

I already have a second career, running a property investment business with a friend.

When I'm done my mixed martial arts career, the only people who are gonna remember me and respect what I did and how I lived my life are my two children. That's my legacy, ladies and gentlemen.
