Spit's Time Travel
Why does our mouth water before we eat?
You're sitting at dinner. The plate hasn't even reached the table yet, but your mouth is already doing something weird — filling up with spit like a leaky faucet. You didn't ask it to. You didn't turn a dial. So what's going on in there?
That spit has a real name: saliva. And your mouth makes about four cups of it every single day, whether you're eating or not. It's basically your mouth's all-purpose cleaning fluid, repair gel, and food processor rolled into one.
