Shaving legs

I have some exciting news my loyal followers! I just got my first B on a test! Not a B-, but a legit B!! Yay! Alright, enough celebration, there's still time for failure. So as we all went through puberty and started getting hairier, we've gained a habit of shaving weekly or often. Your smooth legs, or armpits, or whatever you're shaving is a result of friction. The friction between the blade and your hairs causes the blade to cut your hairs very close to your skin, without cutting it. Another everyday example of friction is flossing your teeth. Your dentist always tells you to floss but why? Because it helps prevent cavities. The friction between your tooth and the floss causes plaque to slide off and not grow into nasty cavities. :)
