Nah, I didn't. The rest of my family has, and I thought I always would, but when the time came up, I thought to myself, "I don't really believe this stuff. I'd just be wasting my time."
I'm not actually a doctor, either, haha. I came up with the name as a kid when I needed to sign up for one of those online game websites to play Monopoly online. :) It was also pretty funny to me a couple years later when I noticed there was a movie called "Dr.Tee and the Woman" (or it was something like that.) I usually just use this name for forums and stuff.
I never had any desire to serve a mission. I've always been really shy, so it would have been torture for me. There was just no way I was ever going on one.
