I'm also very active. Played sports throughout high school and college and definitely miss being competitive. I'm a big runner — just did my first half-marathon earlier this year. Also, i've recently gotten into rock climbing, a sport which I like because it's both cerebral and social.
My family and friends are really important to me. I'm close with a group of guys who I grew up with in Washington D.C. We've kept in touch with a listserv for the last 10 years. The list averages more than 20k emails per year (point of pride).
