People who rarely get sick, what are your secrets?

overuse weakens the immune system

Thank about like this. A lot of bacteria is good for you. Some of it might only providing the benefit of taking up spaces so that worse bacteria won't come in and make us sick.

That's why overuse is bad. It kills off usually less weak "good bacteria" and leaves the door open for some of those super bugs you get in the hospitals.

Kills the good bacteria in your hands aswell.

Antibacterial soap only kills SOME germs. The ones it leaves behind are resistant. You're literally building up stronger bacteria when you overuse antibacterials.

Straight-up cleaning is almost as effective without the riskcertainty of making superbugs.
