I'm one of those forever-exceptions to many rules. I don't doubt that exercise is good for me, but it has never made me feel better or happier. Lots of people report pleasure from physical activity, but all I ever get is pain.
Oh, and no, I'm not a disgusting slab of fat, my BMI is 21.
I used to exercise quite a lot, I know what the runners high feels like and how being sore and able to use motion and stretching to alleviate the soreness felt so good. I could easily lose myself when I exercised.
I don't get that anymore. I have bad joint pains, I never get that high feeling anymore, and everything is a distraction. I want to go back, but whatever happy chemicals used to work no longer do and what's left over makes the whole endeavor feel the opposite.
