Have you ever been tired for so long that you just become no longer tired? Like your body is just like "oh okay we can't sleep yet, keep going buddy." I sometimes get VIOLENTLY tired, usually at work, and then buy the time I get home it's too late... I'm not tired anymore. I might actually have a sleeping disorder or something.
@beardalaxy Yea this happens to me, glad you said something because I was worried. If I don't stop what I'm doing and go to sleep in my tired window, my tiredness goes away and then I have a very hard time getting to sleep. I think it might be a nighttime alertness thing we evolved so if we didn't have a safe place to bed down (caught out on the savannah after dark and not in a tent or up a tree or something) by dusk we'd just crack out and be hyper alert all night long so we don't get eaten.
