My previous misdiagnosis put me on meds that hid my symptoms and covid had my doctor's office telling us that if we had no concerns, to not come in. By the time my symptoms began to show even with the meds, my heart was the size of a football (gridiron football, not association football) and required a transplant. Any increased effort made me nearly pass out.

I get where you're coming from, MOST OF THE TIME diet and exercise are better than not. My circumstances were pretty atypical too, but lets not act like telling anyone that walks into a hospital just needs to jog their ailments away is the way to go. A lot of doctors would do well to try just a little harder, it likely would have saved me from needing to wait for another person to die to be able to continue to live.
