What are some tips how not to get sick and why do we get sick?

Answer 1

There are so many ways to not get sick.Taking your flu shots,tetnis (at least how one person spelled it),and all the other things that keep your immune system up.And Im sure youve heard the rest of these already.
1.Coughing on your arm,not your hands,or into a tissue.
2.Wash your hands before you eat!You do not know what youve been touching all day!
3.Hand sanitizer may help but I dont prefer this because you can become immune to it.
We get sick because our immune systems may break down and infections or harmful bacteria may build up!

Answer 2

Your immune system may be weak. You need to build it up. Eating green veggies and alot of vitiam c helps. But some illness you cant help but get. Like diareah.{haha}
