Shifting topics for a moment, here's a useful op-ed piece in today's Toronto Globe & Mail about the two-way value of masks. The writer is, "a retired public health specialist and epidemiologist... [with] more than 30 years of experience, including 23 with the Public Health Agency of Canada, where he actively participated in previous outbreaks of SARS, H5N1, H1N1 and H7N9."
"Masks protect the wearer, too - and lower our risk for contracting COVID-19"
I, for one, have been surprised the dialog that's emerged over the past few weeks to the effect that masks have value only for protecting others. I ask myself, 'When I'm wearing a mask while I'm sandblasting or spray-painting, am I really doing that because I'm trying to protect someone else?'
