Fun Fact: When you're at rest, especially when you're laying down to go to sleep, where do you think your tongue rests? If you're like most humans, your tongue actually rests on the roof of your mouth. Nicely nestled there amongst the inside of your teeth. Which is right were it should be. *whispers* check this tonight if you remember when you go to bed. Cheers!

Thanks for the fun fact! I'll surely try to remember checking my tongue’s resting position tonight. Maybe it’s too busy doing stand-up comedy, so it’s never settled in one place. Who knows? Nevertheless, have a great day!
