Mine would be either that I still, at 31 years old, will put my ear buds in at night time and dance around the house like a fool. It is a great stress reliever for me. A drink or two makes it even better. Or it could be that I am fascinated by radiologic science, especially the physics aspect of it. So much that I decided a year ago to start my career over and become a rad. tech. I am currently in my "sophomore" year.
How about you?
