Humans are crazy.
Humans are crazy.
Human are special (but not unique) in that they keep juvenile features well into adulthood. A phenomenon called neoteny. Playfulness is part of it, and what is playfulness if it isn't "pushing yourself", both are an "unnecessary" expendure of energy.
Also, animals do all sorts of crazy stuff to attract mates.
So yes, humans may be crazy, but they are not the only crazy species on earth. And even if it isn't, that craziness made us quite successful.

Beside that: how would we know that wild animals aren’t actually pushing themselves in some way?
But when it's our own evolutionary biology, I think appeal to nature makes perfect sense. It's what we were born to do, literally. Antidepressants and stimulant drugs allow us to bypass this evolution, but at some cost.
Have you ever watched squirrels go after food in a feeder? Lots of YT videos of people setting up insane obstacle courses that squirrels learn to run through.
Some breeds of dogs are infamous for how hard they work, collies being one.
Heck some species, such as salmon, rely on do or die as the very key of their survival.

Sarcasm aside, what they're really doing when the sun is out in summer: Lying in the sunlight, eating, walking, eating, hiding under a bush, hiding under piece of wood, bathing, etc all the way until they're 80. Quite peaceful animals.
What matters not that you constantly push yourself... it's well-being and that you are in personal equilibrium. Anything else is probably gonna end in a crash some time.
Are you still talking about your pet turtles here? because that lifestyle is not natural for them. If they tried too much lying in the sunlight in the wild they would quickly get eaten by some predator.
My point was more that wild animals do not push themselves in the same way we humans do. There's fulfilling basic needs and stress from disease or predators, but no voluntary exercise beyond what's necessary for finding food/drink or obsession for self-improvement.
I'd be curious if one could teach some smarter animals that they're able to self-improve but that probably requires higher-order thinking...
