why is strenuous regular exercise considered good for you, but drugs that increase your heart rate are generally considered harmful?

Question

As the title says. As someone with ADHD I’m interested in understanding why stimulant drugs are bad for your heart but naturally increasing your heart rate is considered to be good for your overall health?

Answer 1

Because one activity contributes to the survival of the tribe (strenuous exercise) while the other does not (drugs).

Those who contribute to the survival of the tribe are rewarded through increased strength, conditioning, and overall health.

Those who detract from the survival of the tribe (like doing drugs) are punished through disease and death.

That being said, too much strenuous exercise will kill you and certain drugs are medications which help people. But still, survival of the fittest tribe is where it’s at.
