How would you deal with a Boxer charging in to attack you?

Some Boxers or martial artists may disregard their own safety and charge in wildly to attack you. What would you do? They are many ways to counter. Here is only one. Firstly, do not retreat, which many untrained people do and which gives a big advantage to the attacker. Cover him using "one against two" and strike his vital points, like his eyes or throat.
