What are your hobbies?

I got told in an interview for an internship with a doctor that I should try to find some sort of hobby that I can get to an elite level at- like a D1 athlete, owner of a business for crochet, etc. I don’t really have any hobbies so I am curious what you guys are into? EDIT: to clarify, I am posting because I just don’t have any hobbies and I need inspiration because I think having one would enrich my life and make me happier. I don’t think I need to get to an elite level in a hobby JUST to apply for medical school, I just think it would be fun and I am uninspired.
