I have always covered my mouth when I cough and use handkerchiefs, normal hygiene ( which now seems not to be practiced by most members of the public). My mother's saying was ' coughs and sneezes spread diseases'. I will still be wearing my mask on public transport. The other day, man sitting behind me coughing all over. A mother with two small children, the children, running about the bus coughing all over everywhere. When I was working it really annoyed me the colleagues that would come in with a streaming cold and then pass it to everyone else. Ive always practiced good hygiene, since it doesn't seem to be taught in the home, perhaps it should be taught in schools.
