Anti-Covid-19 mask: 10-cent, 30-second fix

Millions round world chasing anti-Corvid-19 measures. Huge efforts going into masks. Masks for personal use outside high risk areas are of disputed value. But wearing even the most basic cover should help protect others.

So, here's a 10-cent, 30-second solution. Multicloth, cut partly down middle, loosely knotted, easily tied in place and tucked tidily about mouth and nose.

It will of course be much more effective if everybody out there keeps their distance. Which, in my part of Australia, many, specially men, are not.
