How do you know you can take a punch?

Question

tell me please

Answer 1

Because I have.

Answer 2

It really depends on your constitution.

If you are generally healthy and tough, odds are you have an iron jaw.

If  you are often sick, and get sick frequently, likely you've got a glass jaw.

Answer 3

Let someone hit you i guess

Answer 4

Best way is to get in a ring with the gloves on and go at it! The only way a punch will hurt is if you're afraid of getting hit! U have to be willing to take the hits or don't bother trying.
