There was a Joe Rogan podcast that was focused solely on the topic of how essential physical activity is for people. There he [Rogan] explained how there was actually some sort of scientific research which showed that people who exercise regularly have much better neural function than those who didn’t.
He said how working out helped him stay young and also said that there are days when he doesn’t feel like going to the gym but the satisfaction he knows he’ll get after completing that workout is more than enough to motivate him.
In the podcast itself, Rogan said that some medical experiment was conducted which actually helped people to transform their mentality. A woman, who was the subject of the experiment, never felt the motivation or need to go train or even enter into a gym, but said that after the experiment, her mentality changed completely.
Rogan also explained that one of his friends who was actually a smart and intellectual guy also didn’t accept the idea of exercising but Rogan said that the human body is a like a carrier and exercising means we are taking care of it otherwise if this shuts off, then other activities will also shut down automatically.
