When I have down time I like exploring, either in the city or jogging around LI. I go for a long run at least once a week and have been trying to get into the NYC Marathon for the past few years.
I'm also pretty fond of the arts, especially film. Visiting new museum installations/galleries or catching a movie usually top my list of things to do. I usually favor well rendered, detailed work over abstract/minimalistic pieces.
Movies: Gladiator, Watchmen, Finding Nemo, Pineapple Express, Surf's Up, Dead Man's Shoes, Amélie, Oldboy, Butch Cassidy and the Sundance Kid, CJ7, The Presidents Analyst, The Girl Who Leapt Through Time.
Books: I'll wait for the movie. (Except if those books are the Twilight Saga or The Hunger Games.)
Food: Baby Carrots, Edamame, Omelets, Popcorn, Greek Yogurt, Kashi Cereal.
