I quite like modern social and political history (think Thatcher) but I'm doing my EPQ on medical developments in the renaissance/middle ages which I'm also finding really interesting, although it's really similar to the medicine through time topic I did in GCSE history so I knew I'd enjoy it. I have a friend whose applied for vet med, not something I'd fancy but I suppose that at its core its about helping people (and animals) which is applaudable, I guess there's also room for some quite interesting stuff you can do, like dealing with exotic animals.
