Art; Music; Engineering &Technology; Robotics (particularly the FIRST Robotics competition, for which I coach a local team); and Politics.
Differnt people. One caveat: anyone I meet must understand and accept that my sons come first in my life.
Rock, almost any kind. I like to stay current, and pay attention to "modern" music.
Too many to name. I like movies, and enjoy going to the cinema.
Don't watch it all that much. Dr. Who on Sci-Fi.
Way too many to really list, but some favorites are "Look Homeward Angel", the "Dune" series, books by Jodi Picoult (who is a local author and generally nice person), sci-fi by Allen Steele, Neil Stephenson, Frank Hebert and other greats in that genre.
A few people who I know are heroes to me. Because they are real people, and mostly private, I really don't feel comfortable naming them, since they might feel embarrassed (and I don't want to swell their heads). I can say though, that they've taught me much.
