Sometimes I'll drink water directly from the faucet.
Why do you drink water directly from the faucet?
I heard that it has negative effects, but I do not care/
There's no reason to ever put your mouth on any faucet as that's extremely unsanitary and not kind to the others who may be using it in the future. You should instead fill up a cup or mug with water, or else you will be upsetting a lot of people.
It's fine as it is not on it long.
It only takes a second to expose the faucet to germs.  Think of how you feel if others did that before you?
