IMHO, and it is just one opinion, at least one of your items should be something unrelated to medicine or science. For some people it will be athletics, for others arts (performance or studio arts), or an off-beat hobby (jewelry design or motorcycle repair). Some people will shy away from listing anything having to do with religion or politics but for some people it has taken so many hours per week for so many years that if seems odd not to include it. Whatever you list, I'd suggest that not more than 20% of your items be athletics, arts, hobbies, etc. If it gets to >60% it starts looking like filler. Same goes for listing things that you did for a very, very short time like being engaged in a soup kitchen once a year to serve a holiday meal.
