Yes the mask thread has been exhausted I agree, but I think wearing masks is eesential to keep the economy going or shops are going to close and people will feel they are in lock down again, buying on line, not going out etc that is not the way,people will feel isolated again, and in the end people will not go out, how sad is that.You must try to wear a masks indoors for quite some time first, then it may be easier when in shops,give it a try.Its ok for me to say as having been a Nurse all my life I have worked many times for hours on end, with a mask on, you really do get used to them. Please dont shoot the messenger!
