Using hand sanitisers whenever I pass one helps with that problem - even if it does dry the skin on my hands. My better half has a bigger problem because of eczema from skin allergies. (does anyone know why we say exma and not exzeema - decades of lazy speaking?). Surely the answer in favour of masks is that if we cough on someone, the droplets have a much higher viral load than if we breath on someone. I still find it ridiculous when people still spout on about masks being impervious to oxygen and carbon dioxide. Maybe they are using polythene masks???
