Answer 1

Answer:

Did you wash your hands? Did you use soap?

Children everywhere are grossly familiar with those questions, but it's for a good reason: Washing with soap is essential for preventing the spread of germs that make us sick.

Germs, or microbes, are everywhere. Literally, everywhere. In the air, soil, water and on every surface, including your body. Most microbes are harmless and some are important for human health, like the ones that live in our gut. But there are several germs that cause problems, and these are the ones we prefer not to have on or in our bodies. Our first line of defense against those harmful germs is soap.
