inhabitable means habitable? what a country!
I think you mean uninhabitable.

There's a difference between being able to able to prevent eh passage of a bullet, and being able to absorb the impact of a bullet. While I don't doubt the idea of being able to create a t-shirt that will prevent a bullet from passing through, the kinetic energy of the bullet will still be transferred to the target. Traditional body armor is designed to absorb this energy, but something like a t-shirt could not. Just a thought. Maybe if you had a bulletproof t-shirt over a ton of padding!
