While I believe that masks do help reduce the spread of viruses, I'll play along that there is no science to back up that statement. Humans do not only do thin

While I believe that masks do help reduce the spread of viruses, I'll play along that there is no science to back up that statement. Humans do not only do things because they "make sense" / "scientifically proven", many times we just do it because its low effort and helps make other people feel comfortable. Its like smiling when you see a stranger, or saying good morning to someone. There is no sense to it, you don't plan to stop and chat. However, it breeds a comfort (and eventually a distant camaraderie) because a greeting means a lot to them. Typically a greeting signals (sometimes falsely) a lack of malicious intent. Given they are a team all sitting in the same room, even if one of them is more comfortable with masks on (logically or illogically), its just a kind thing to do for each other. Much like choosing to keep your cellphone off in a theatre, choosing not to smoke while in a group on non-smokers (outdoors or indoors), choosing to let everyone else exit an elevator before you, or choosing to respond to a comment you know is likely better left ignored :). I wish you the best of luck in the future, and hope (masks or no masks - whatever strategy to help others you choose to use) you use some small amount of your time/effort to help make other people's lives a bit more comfortable.
