When someone near me sneezes, I hold my breath.
Can you explain to me why you hold your breath?
I don't want to breathe in their germs when they don't cover their mouth and nose.
Holding your breath when others sneeze is not a thing most people do, but it's okay to protect yourself and not want to get sick. Getting sick has many negative consequences, including being unable to work.
I think sneezing is less harmful than touching, as that's the way most germs are spread.
Germs are spread in many different ways and I think it's a good thing that you're aware and try to protect yourself from getting sick. Practicing good hygiene and avoiding situations where there are sick people is a good way to help prevent the spread of illness.
