Before we proudly push for ancient ideas, lets not forget that these same greeks selfishly advocated for slavery so that they themselves didn't have to work and could pursue education and physical activity.

Another ancient greek idea was forcing people to commit suicide via hemlock ( as what happened to socrates himself ).

Another ancient greek idea was that women were incapable of being equal to men and being educated.

Another ancient greek idea was a form of pedophilia.

I'm for working out and educating oneself. But lets not cherrypick ancient quotes as use them as justification for anything. It's a form of appeal to authority.

How about working out is good for your health and education is good for the mind. No need to appeal to the ancients. Appeal to facts instead.
