I have many eclectic interests so it's really difficult to pinpoint anything. I'm a big gamer at this point. I think tabletop games and video games as well can be used for entertainment and also for training the mind.
On the side I started working on my yoga practice. I took some time and am now a certified yoga instructor at the 200 hour level. I need to continue my own personal practice, but I also want to create a yoga program that integrates various concepts from Yoga, Tai Chi, Taoism, and science.
In the meantime I'm meeting people and writing a political blog: http://politicoid.us/blog
Movies: Man from Earth, Evil Dead (all of them), pretty much all of Miyazaki's movies, Paprika, pretty much anything by Mel Brooks, What dreams may come
Shows: Doctor Who, Sherlock, Stargate, Star Stek, Bizarre Foods, Chopped, Firefly, Trigun (obviously) as well as similar series like Gun X Sword, Cowboy Bebop, and Outlaw Star...
Games: Tsuro, Small World, Munchkin, Ticket to Ride, Settlers of Catan, Elder Signs, etc
Food: Almost all food. There is almost no food that I won't try, and I find that I like quite a few types. On the top of the list is salmon sushi, uni, a really good steak, pasta, and a lot more.
Drinks, etc: I consider a good drink and a good cigar to really complement food well. I like a nice scotch or a good cognac. The best cognac I've had to date is Tesseron lot 53, but I really want to try to Extreme (when I'm rich). As far as cigars go, my choice is a medium bodied cigar. Also love a good pipe tobacco as I've mentioned elsewhere I think. My favorites include blends of Virginia and Black Cavendish.
