10 Hours, Raz!! I hope you don't mean EVERY day. That's way too much for an average human. 😂
If I get a good 7 hours worth of sleep, I'll be good and dandy for the day. If I get 6 hours, I'll still be fine. But 5 hours or less, and I'll slap the crap out of you if you talk to me more than 20 seconds.
