Astoness I think it is a very good idea.
I remember when I was at Cromwell street school in the 50's, each morning after assembly the head mistress would always inspect each childs hands for cleanliness or dirty fingernails, their shoes to see if they were clean and polished and she also checked whether you had a handkerchief.
Those who didnt were taken out of the lineup. I never knew what the consiquences of disobeying these rules were as my mother always checked us kids over for the above items before we left the house for school.
In junior school we were taught how to use the handkerchief and to move away from anyone sneezing and cover your nose with the said hankerchief. We all had to all chant a rhyme ' Coughs and Sneezes spread diseases, please use your handkercheivses' or something like this.
I think everyone in those days was careful about germs because antibiotics which were expensive and new were only used for bad infections so people still relied on the old trusted methods of cleanliness to protect their families from germs as much as possible.
In Birmingham there was of course the scares of smallpox (I think this is the correct illness as I remember being inoculated with my brother at the GP surgery on Nechells park Road) and TB (which we were also inoculated against at school when I was about 14 ) but anyway keeping things clean was a way of life in those times.
We washed our faces and hands or even had a bath (in the tin bath in front of the fire) with Lifebouy soap or coal tar soap, only when we were teenagers did we discover the perfumed soaps. Hand washing was with cold water as few houses had hot running water.
For the floors in the house we used bars of rough carbolic or bars of Fairy soap, a drop of dettol disinfection if you had any , plenty of very hot water in a bucket, a scrubbing brush and an old towel as a floor cloth oh and newspapers to step on while the floor dried.
Clothes especially white cotton ones were soaked in an enamel bucket with a lid or the boiler with bleach and or washing powder. We also had a special saucepan which had been mended with a metal washer which we used to boil large cottton mens handkerchiefs especially when the flu was doing the rounds. This killed off all the germs and kept the washing white at the same time.
In the senior school we learnt how to top and bottom a house and clean it methodically in all the corners and on the tops of wardrobes etc and to look after food properly to avoid food poisoning.
