Dated a vegan with a closet full of running medals. She literally had a closet bar dedicated to those and nothing else on it. She jogged 5-miles a day as her normal routine. At 51, that woman was ripped.
Unfortunately, vegan and (I forget the word about living a simple, stuff-free life) was about all she could talk about. She had very little interest in anything else, but was nice to enough to listen to my ramblings on all the things.
