Generally, I agree, but "feels good" doesn't translate well between individuals. To many, eating a jelly donut "feels good", at least in the short term. Most people don't excel at long term thinking, and so whether one feels good probably isn't a great metric for whether one is doing something beneficial.

Another thing is that I personally wouldn't consider 4 out of the 5 things you listed to feel good, and in a few cases I don't even find them to be linearly beneficial. The kind of cardio exercise you mentioned (all exercise is cardio BTW) is something I don't enjoy before or after. Things like bike riding have both positives and negatives, and I am not a fan of the high cortisol state that results. I'm not saying riding bikes is bad, but if I was totally oblivious to the health benefits, I would find it to be a slog once I got over the novelty
