I think its normal for modern society, I can't speak for you guys, but for me, lifestyle plays a big roll. spend all day sorta taxing the brain with legit fast paced multitasking in a high tech world, then by the time you get home and you 'should' be tired, you haven't done the primal tasks that make us legitimately tired. I get more like that Mon-Fri when life is mostly computer work.
Sat/Sun when I spend the day beating my body down with farm work, shoveling yard after yard of soil etc, I'm exhausted, have a big meal, and sleep like a baby. its a totally different kind of tired from hard manual labor vs all day whitecollar bs. Its healthier I think... also harder in a way, IDK. Like who TF chooses this in a day and age where uber can bring me food while I play video games? lol
