When it really happens: SHTF...

[Surpmil]

Turning up the heat and opening a window most distant from one's bathroom(?) extraction fan(s) and getting some through-flow of air can help, depending on the outside air quality of course, but if central heating is present and has a humidifier built in, clearly turning that up to raise the ambient humidity to 50 or 60% will dramatically reduce airborne survival times for virus particles. The old vaporizers would work well too. Higher humidity should also help to keep bronchial mucous fluid as well, which white blood cells can apparently move through if it is sufficiently liquid.

Might be the time for those fabled eight glasses of water a day hardly anyone remembers to drink!

Remarkable book.
