Should you actually wear a mask?

Before COVID hit we didn’t wear masks, but why? There were still illnesses like flu and colds, but how come we didn’t wear masks? Even though we didn’t, some people from other countries did. Why did they? Why did we stop wearing masks since we wore them before during the 1918 Spanish flu pandemic?

We now wear masks on a daily basis. It is now as normal as eating. We are now leveling down and might get rid of masks. It has gone on and off. We haven’t worn masks recently because they weren’t as severe. Others wore them because they were being careful. I’m guessing that they stopped wearing them because it slowed down. Even before we all thought that it could never happen and that it is crazy. What is crazy is that after this we won’t wear for maybe 100 years.
