I didn't fully appreciate our mouth's tolerance to temperature until I was lazy the other day and used my finger to stir some tea instead of going back to the kitchen and getting a spoon.

Blazing hot for a finger, nice and refreshing for a drink

    Gonna suggest it's less simple than that. The mouth only touches a small amount of fluid at once. The temperature plummets really quickly when you sip the hot coffee.

    When you stick a finger in the coffee, there's a lot more coffee keeping the liquid contacting your finger hot. That's why you sip hot coffee. If you do a quick dip with your finger, it won't burn.

    It's similar to how you can accidentally brush a hot pan and not get a burn.
