Is the last sip of your drink really spit?

The idea that the last sip of a drink is "spit" is a bit of a myth and a humorous exaggeration.

Here's why:

* Saliva is always present: Your mouth is constantly producing saliva. When you drink, you're not just swallowing liquid; you're also swallowing some saliva mixed in.

* Swallowing mechanics: Your body doesn't actively spit out the last bit of a drink. The muscles in your throat work to push the remaining liquid down.

* Taste buds: The last sip often has less flavor, but it's still being processed by your taste buds, just like the rest of the drink.

So, while the last sip might contain more saliva than the first, it's not considered "spit" in a literal sense. It's simply the final bit of the beverage mixed with your natural saliva.
