If you're yawning, sluggish and can't focus, those are some of the obvious signs that you're not sleeping enough. But there are less obvious signs you might not know about.
I didn't know I snored until my wife told me. Maybe the only good thing about being a person who snores is that you're the only one who doesn't hear it.
I woke up this morning after four and a half hours sleep and thought I was tired. Then Liz walked in and said she only got one hour of sleep. Time to get through another day with a serious lack of sleep. And a potentially cranky co-worker.
It's definitely happened to you...you finally fall asleep and **ring** **ring**. You wake up in a stupor trying to figure out what that sound is, squint at the clock, and groggily answer the phone.
"Hello?" "Oh...were you sleeping?" "IT'S 3 A.M.!!!! WHAT DO YOU THINK??"
When it comes to phones, do you have a time limit?
