If the coronavirus pandemic of 2020 has taught individuals anything, it is a better understanding of how the air breathed in and out of our lungs can affect us and those around us. Masking, social distancing, and quarantining -- all to keep a tiny virus out of lungs. Experts remind us that lungs can be vulnerable and need to be kept healthy so they can keep us healthy. One of the best ways to keep lungs healthy is to never smoke or vape. And if individuals do smoke or vape already, the best thing to do is to quit.
