Yeah I think those 2 things would count. I listed reading as a hobby because I LOVE LOVE LOVE reading--I know I'm a huge dork--and fitness/nutrition because I have spent most of my college career really learning about nutrition, diets, and exercise because I did some modeling type things. I did NOT, however, include the modeling stuff or that I had won Miss Photogenic at a pageant (or even did a pageant, though if you actually won first place I can see where you'd want to add that) because my advisor told me that last year, a girl from my school was interviewed for OSU and was basically torn apart for being a bartender while in school. They kept asking her if she really thought this contributed to her future vet career. Although I don't bartend (b/c I don't drink), that is definitely the best paying job in town you can get without a degree or something similar. This is a huge party town and bartenders can take home sometimes $200 a night, so I totally get why she was doing it but they were NOT impressed to say the least. She did not get in, in fact, and was a pretty darn competitive applicant. I do believe that winning that title and doing the model stuff contributed to my future career because of several reasons, but I don't know if the adcom would agree.
Just thought I'd suggest what you might not want to add too, just in case🙂
