Yeah, getting obsessively into some kind of physical activity that gives you dopamine beyond just the basic "after workout" happy chems will absolutely transform your body. I started aerial arts at 33 after 3 years of being almost completely sedentary post-autoimmune-diagnosis and am closing in on 2 years now. I look and feel a million times better and I need to eat way more to keep up with my 8+ hours a week of intense acrobatic and calisthenic workouts xD

Down side is that if I can't go to class I'm a grumpy bitch, lol.
