Red pill me on gut flora

How exatly bacteria interact with human body and make them sick?

If you wave your hand in the air, do the bacteria and viruses on the surface of your hand's skin go flying everywhere or do they cling to the surface?

Hello /sci/,

Can you educate me on bacteria?

So I understand that they are everywhere but what I don't understand is WHEN they are harmful for our health. Does there need to be a certain amount of a certain bacteria before it gets harmful or do the odds simply increase with the numbers?

How much of them does normal soap remove? How much does alcohol disinfectant remove? Do both just decrease the odds?

How far does bacteria spread out and how long does it survive on an inorganic surface?

Thanks.

I don't understand these little shits.
Can a bacterium be on top (stacked) of another bacterium?
If you contained a shit ton of bacteria in one place all pilled up could you feel them?
