#10: Lunar Languish
One person noted their tongue isn’t smooth but has cracks and craters, thinking it was unusual. Actually, the average human tongue isn’t smooth but is covered in tiny bumps called papillae, crucial for taste and food handling. A completely smooth tongue is rare medically, highlighting the fascinating diversity of human anatomy.

Papillae contain our handy dandy taste buds and help us grip food in our mouths. They’re pretty important. We’re guessing this person pointed out their tongue as a medical anomaly because it appears bumpier than the average person’s tongue. We’re a bit concerned. Maybe this person needs to drink more water and see a doctor.
