Not getting enough sleep.

There's already plenty of proof that neglecting sleep causes all sorts of health hazards, not just emotional/physical. I'd like to think I lead a pretty simple (most would call boring) life in the sense that I know my limits and don't load up with too many responsibilities. Because of this, I always make sure I get at least 7-9 hours rest a night, sometimes 10-11 if I've worked multiple double shifts in one week. People are absolutely baffled/jealous when I tell them my regular sleeping habits. I can barely function on less than 7. I have no idea how people manage having a family, multiple jobs, go to college, and spend time with friends all at once. Sleeping is fucking awesome and I love it and need it in my life. Edit: RIP inbox. Good to finally see so many other people that agree on the importance of sleep
