Are you really sure there's no bacteria there? Unless you absolutely drench it in alcohol, there are very good chances something will survive. Even the meat itself it's going to be completely sterile unless it's burnt to a crisp. And ask yourself about other things, what did you use to transfer the meat to the drawer? Doesn't matter if it's only a couple cells that survive, they will immediately get to work on the steak and soon you'll have an entire colony.

And yes, they can also be blown about by air currents and land on the steak, they can do without food for a couple of minutes.

Bacteria are a singe celled living organism that's not that dissimilar from our own cells.

They are everywhere all the time. Nothing produces them, they are living things and multiply on their own. They don't mate and have offspring like animals, they use binary fission and essentially just grow another one of themselves and then split into two.

Copy protection is a wide industry that specializes in doing just that. There's hundreds of different ways of achieving it, so you'll have to look up specific consoles or even specific games to learn more.

In the case of your CoD dvd, the disk doesn't even contain the game, but only some information to take you to the download page and maybe an activation code.

>Anyway, i'm still MEH on calling it a "sport" because is on the same level al esports and Chess for me.

motorsports are extremely physically demanding, way more than some "proper" sports. You should go drive gokarts some time, when you're exhausted and sore after half an hour, try to imagine doing it at 10x higher forces and for four times longer.

Plus some categories still have direct steering, which means just turning the steering wheel is super hard, it's not uncommon for Indy drivers to have blisters on their hands after some races.

Fun fact, there are breeds that lay blue and even green eggs.
