You will probably decide on other items to protect you from the paintball that can hit you at a speed of 300 feet per second or about 205 miles per hour. This speed is checked in most fields, perhaps a couple times a day. Yes, some hits can sting for a few seconds and can leave a welt and maybe black and blue in a few days. Knowing that makes you take the whole thing more seriously. Knee pads and armored gloves are a good idea too.

A single shot a time may make it a bit more difficult to stay alive for very long. This is the type of gun most commonly found on the field, both rented and privately owned.

The mental attitude and ability to plan your course of action to survive has no bearing on gender.
