Simple: **Touch your face** to remove your mask every time you need a sip of water. Oh, also- **touching your face is the surest way to catch a disease.** Someone coughs on their hand, opens a door, three minutes later here you are opening that same door. Then your mask is making your chin itchy. You scratch your chin- congrats, you've just likely contracted w/e was on that doorknob! But non-stop mask-wearing is good for you.
