I also have a natural curiosity about almost everything, and I've always liked to learn how things work.
The Dune series, 1984, Hitchhiker's guide to the galaxy, Rendezvous with Rama, Timeline, anything by Arthur Clarke and Frank Herbert. Don Quixote, Anna Karenina, Mark Twain's autobiography, a 3 part series on Theodore Roosevelt, and Knocking on Heaven's Door by Lisa Randall the theoretical particle physicist.
Star Wars, Back to the Future, The Right Stuff, Terminator, Twins, True Lies, Apollo 13, From the Earth To the Moon HBO miniseries, John Adams HBO miniseries, The Big Lebowski, Indiana Jones, James Bond movies, Crocodile Dundee, Goodfellas, Office Space .
The Daily Show, Last Week Tonight, The News(gotta stay up to date!), PBS documentaries and Discovery channel shows that delve into the mysteries of the universe.
Mostly rock and/or roll, metal, classic rock, indie, and the like. Any type of 80's music with cool guitar licks always grabs my attention. I can usually listen to just about anything except some hip hop, and R&B.
Most anything although I tend to avoid heavy or fatty stuff like cheese, cream, desserts (though not all the time),and some types of seafood.
Keeping my mind active
