Very good point: while it is common sense and true that exercise reduces ADHD, it is also common sense (but not true!) to say that sun revolves around the earth

Very good point: while it is common sense and true that exercise reduces ADHD, it is also common sense (but not true!) to say that sun revolves around the earth or that, in a vacuum, a feather will hit the ground after a large ball of lead. Much of Quantum Mechanics is also counter intuitive but true, while some scientific concepts can only be expressed through mathematics and have no simple intuitive explanation.
