Even though we are often very close to other people that may be sick, we do not always get sick as well. Why? Guys pls help me!!!

Maybe because we are carriers, and it doesn't affect us, or maybe because we are immune to the sickness, those are two reasons it might be why we don't get sick around others that do get sick.

a chair, a bed, and a toothbrush

explanation:

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
