Better have him be careful. A couple of kids in china have died doing p.e. With masks on. Another lady, here in the states, asphyxiated herself while driving a long distance across the US. Ended up passing out and wrecking her car.
No n95 type mask is meant to be worn for extended periods of time. Think about the painter for instance. He wears it while spraying but takes it off when he is not spraying. A doctor removes his between every patient, room, ect. These are times when the human body is not being inindated with co2.
With your fathers advanced age, he may not want to be doing his exercise with a mask on. It may very well be more dangerous to do so.
That was my point. This busybody may have thought she was doing a good deed but is actually doing harm. It’s a cotton mask which provides no protection but. is he thinks he needs to wear it to not hurt her feelings. People need to mind their own damn business
True on the N95s although most people if they get one don’t wear them appropriately. I’m good for about 15 min tops. Then add a full face shield and it’s even more difficult/
