The surfaces tasks give yourself something, an arduous, difficult task where you're challenged, challenged mentally and challenged physically. One of the great things about being challenged physically is it's also mental. The people that don't understand that have never really been challenged physically, people that think that physical challenges are just, like, just physical. It's just brute grunt work. It's not. It's emotional intelligence. It's understanding your desire to quit and conquering your inner bitch. All that stuff is mental. It's playing out inside your head. And there's a mental strength that you acquire from that, that you can apply to intellectual pursuits. And the people that don't think that are the people that haven't attempted them. And there's an arrogance to people that only pursue intellectual exercises, only pursue intellectual things, and don't pursue anything physical, that the physical stuff is base. It's grunt work. It's primal. It's not necessary. I don't think that's accurate. I don't think that they're. I mean, obviously, these people like Stephen Hawking's, who have no opportunity to do anything physical, right? His physical dilemma is keeping us, or was keeping his heart beating. But for most people, I think you can really benefit from physical struggle, and you benefit from it in a mental way. And I think that is overlooked, that's unfortunately overlooked by academics and intellectuals who they make excuses for, why they're fat and lazy or scrawny.
