Hi michie,
You do know that you don't have to wear the masks outside, for the most part. Only if you're in a crowd of people. Me, I carry my mask in my pocket and just before I go into a store, where it's generally nicely air conditioned, I put it on. I don't wear it every minute of the day and you don't have to either. Whenever you are inside or expect to be within 6 feet of someone, you should wear the mask.
However, it does take some getting used to and there are different masks. Some do make you feel fairly claustrophobic. Some are harder to breathe in than others. I like the masks that are advertised on ebay for $10-15. They have two breathing ports to make breathing easier and they don't quite fit flush to the face like some of the buy in 50 bulk paper or thin material masks. This is what I have:
It has a nice heavy velcro style neck band and the ear loops. You can buy replaceable filters for it and it's washable.
Hope that helps.
God bless,
In Christ, ted
