I'm now learning how to distinguish when I'm acting and when I'm not acting - offstage as well as onstage.

Many people have fond memories of 'The Monkees.' I fondly remember it, too.

When my 'Scientific American' arrives every month, I read it cover to cover.

The Rock and Roll Hall of Fame is not a public democratic organization; it's a private club basically. It's like a private golf club and they decide who they're going to let in the club.

I could write historical fiction, or science fiction, or a mystery but since I find it fascinating to research the clues of some little know period and develop a story based on that, I will probably continue to do it.

I have come to understand that my hatred of the gym was based on fear and prejudice, a tribal resistance to science, to improvement. But to ignore my aging physicality and not try and become the strongest and fittest I can be is curmudgeonly at best and wilfully ignorant at worst.

In these days when science is clearly in the saddle and when our knowledge of disease is advancing at a breathless pace, we are apt to forget that not all can ride and that he also serves who waits and who applies what the horseman discovers.

The time has passed in the history of the world when anything is too sacred to be touched, when anything is beyond the reach of the inquiring and scientific spear.
