Canada. Makes no sense to wear masks *except* when you are breathing most heavily. (I know of gyms in the US *still* with similar rules: Must wear a mask to come in! Sanitize your hands before getting on the elliptical! Then you can take your mask off while you huff and puff.

Check reference 143, "World Health Organization 2020 guidelines on physical activity and sedentary behaviour" 10.1136/bjsports-2020-102955 Nothing about face, mask, nose, mouth, COVID, SARS, infection.... nothing that appears to support the reference. /2

Not using mask could adversely impact your or others ability to breathe, period.

Is learning not possible? Why is it so difficult? Huge outbreak at spin club just a short distance away in October.https://www.cbc.ca/news/canada/hamilton/covid-19-spinco-outbreak-graphic-1.5767688 …

It's so absurd. Faced with this massive spin club outbreak what did the province do? It increased the distance for group aerobic activity from 2m to 3m. Still permitted to remove masks.

This is horrible. Get a reusable mask http://patientknowhow.com or Aaron collins has great data. Many effective masks with min. effect on breathing (pressure drop), don't collapse in on breathing, and have excellent filtration > 90%https://docs.google.com/spreadsheets/d/1ZEK83iVm380-p1ODJ3j5iHyHtNugLPdxmnMLhvbb8DQ/edit?usp=sharing …

I don't think Wuhan Health Organization has any credit left to recommend anything regardless if they are right or wrong, no point quoting then anymore, discredited for years.
