Catnaps rule! Even fifteen minutes makes a huge difference in your ability to function. Soldiers and new parents both learn to sleep anywhere, any time out of necessity.

You guys doing long drives on little sleep, if you can't actually stop and get a full night's sleep, pull over every now and then and take a quick nap in your car. You and everybody else on the road around you will be much safer for it!

"I'm wondering if our farming ancestors back in the day when everyone farmed ever suffered from burnout."

Probably not, since they could see tangible results from their labor. Ever done farm work? It's harder than coding, I can tell you! But it's also very satisfying.

If they worked hard, and the crop failed anyway, then they had MUCH bigger worries than their state of mind!
