Yes
A good way to protect urself playing airsoft is by using glasses to protect your eyes, this is the most important. A thin shirt and some shorts will do.
If you are talking about the safety glasses then they are not specifically meant for airsoft, but they should be strong enough to protect against bb's. I would strongly recommend using either full seal goggles and a lower half face mask, or a full face paintball mask, as glasses alone allow bb's to enter from the sides or top in some situations. Lack of lower face protection allows for getting hit in the tooth with a bb, which will cause permanent damage to your teeth.
no dirt bike gear is just a helmet and jacket, but paintball gear is a helmet a paintball gun and padding
Your Eye's are important to you. They are all you have, do you want to risk that to save a few dollars. Don't be foolish.
No, it keeps the body cool under the normal range of temperatures experienced on Earth, but would not protect you from the extreme heat of a fire.
It would be foolish to do so. Always protect your eyes.
They don't protect their young they have to do it by themselves
How to properly maintain your gun, gear, how to protect yourself (glasses, facemasks, etc)
Not really. I mean it stops an airsoft shot, but it will not properly defend you during a terrorist attack, or nuclear fallout You can buy airsoft plate carriers, which could technically hold bullet proof plates in them, but they are not meant for this and should not be used in that way. But you can buy airsoft proof plates which will absorb pretty much the whole force of a bb's impact, effectively protecting you from airsoft guns if that is what you meant.
We wear clothes to protect ourselves from changes in temperature. This is a simple sentence. The clothing serves as a barrier to shield us from both extreme heat and cold temperatures. This is a compound sentence.
No, birth control pills DO NOT protect against HIV
