What I'm going to say is aimed at all applicants:
You shouldn't feel the need to try and find "medical relevance" in your non-academic activities and hobbies. Doctors are humans and med schools want humans to fill the slots in their entering class. Humans have hobbies and interests outside of their jobs. This is one of the main things that separates us from robots, and that's a good thing. Why? Because robots make terrible clinicians. Robots would probably make decent surgeons, but that's a discussion for another thread. The point is, med school admissions committees know that robots make bad clinicians, so they welcome the chance to learn about your hobbies.
Bottom line: they know that you don't play poker because you think it'll make you a good anesthesiologist. They know it, I know it, and you know it. But that's OKAY.
