Edit. Shadow. Mindmaster (#26) said it better than me. Nothing wrong with masks. Just the judging and negativity surrounding it is terrible.
Most people have to go around ithers at some point for whatever reason. Such as to the grocery store. Or for medical appointments. My own personal thing is going to the gym to use the elliptical to and a no-impact aerobic workout given my bad knees, and that is after I asked my doctor for his input about, which did include wearing a sweat band and putting my hakr in a ponytail so I'm not wiping sweat off my face, wearing gloves, and wearing a mask. Breathing is difficult at times, but like anything else my body is adjusting.
I'd try not to compare bodies, though. General health, age, location, are factors. For example, I have seizures so I sometimes have seizures running or on a treadmill (any cardio). I don't wear a mask because I get dehydrated easily and all that together but to wear a mask "just in case" I cough or sneeze at someone ten feet away from me is ridiculous. But masks do make people
feel safe regardless what the mask itself is intended to do or admit it or not.
The thing I have an issue is why people have so many negative feelings about people wearing "and" not wearing masks. Emotions affect me mentally and physically. Now, I get it if someone was in people's faces. Some people like to reach over my shoulder to get food off the grocery shelf when they could wait a couple seconds for me to move out their way. Masks may help but social distancing (don't get near me) helps a lot more.
The emotions people have bother me the most more so than the virus and masks and so forth.
But this asymptomatic thing is what's causing much of the fear. Gosh. I'd be a hypochondriac if I kept thinking I'm asymptomatic to every other virus we haven't yet cured and can treat. Masks shouldn't be used to hate and judge others. Fear is highly contagious. Most people have small symptoms if they do catch the virus but fear... that's a whole 'nother animal.
