Do you have any funny cold knowledge?

When we eat pineapple, pineapple is eating our tongue. The reason why we feel tongue pain when eating too much pineapple is because there is a special enzyme in pineapple, which can consume some cells on the surface of our tongue and make us feel that eating too much pineapple will hurt our tongue. A good way is to slice the pineapple, then prepare some salt water and soak the pineapple in the salt water. When eating it again, it will do much less harm to our tongue.
