Masks don't protect the user.

Wear a mask all day, you will notice it will be warm and moist. Air will go through the path of least resistance but the mask will catch a lot of moisture you exhale thus reducing the amount that is put into the air.

My grandfather used to be a Train Driver in South Africa. This was during the period from about 1960-1989. He was a good Train Driver, probably the best there was in South Africa at the time, never late for work, always did his job. It was his favorite job actually, not because of the beautiful scenery and relaxing environment of the front drivers cabin with the amazing view, he did not do this job because of the reasonable and stable pay packet, he did not do this job because he liked to choo-choo all day long and transport humans from Jo-burg to Durban, he did it because he wanted to see how many Niggers he could hit with his train before he retired. In 29 years of loyal human transporting service, my grandfather managed to hit and terminate 27 Niggers with his big giant and invincible-to-niggers train. They all died, he made sure never to brake. He told me that once he hit a big fucking she-kaffir baboon, probably weighed around 400 pounds, and when he stopped the train to inspect the damage to the front of the train he says that he could not find one piece of nigger flesh larger than a handful. This fat fucking nigger exploded into thousands of tiny little yellow pieces of flesh and fat, the train hit her so hard. Hardly left any damage to the train except for the messy cleanup of removing nigger entrails from complex white mans choo choo machine.

Damn I totally though Eli Whitney was a black man too
