    they are still more effective than no mask at reducing the spread of airborne particles from the wearer.

    Yes, but the wearer has it on their chin.

    The theoretical effectiveness of masks used in best practice and the actual effectiveness of actual practices are often miles apart.

    I’m not anti-mask at all but from a public policy perspective the overall effect was meh.

    I don’t think how hot humans feel works at all, it’s just arbitrary

    Fahrenheit was originally calculated to be 64 even divisions between water freezing temp and human body temp, then 32 more units below freezing.

    Then ambient human body temp was recalculated from 96F to 98.6F.

    So it’s not exactly arbitrary. It’s based on powers of 2, based upon an inaccurate measurement.
