In my early 20s, I got tinnitus even though in the rare occasion I'm around loud noises I wear hearing protection. In my mid-late 20s, my vision got worse after never needing glasses and my knees starting creaking with occasional pain. I now need some more involved dental work even though I brush and floss regularly. I've lived a predominantly outdoor, active lifestyle the last several years, so I *should* be quite well off health-wise, but it still feels like I'm aging faster than I should be. wtf?
