Germ-Less Kissing Using This 1920s Device

Germ-Less Kissing Using This 1920s Device

A 2009 study suggest that the act of kissing might be important because it helps us build up our immune system – specifically women during pregnancy benefit from this strategy. The study was published in the journal Medical Hypotheses.

Researcher Dr Colin Hendrie from the University of Leeds said: ‘Female inoculation with a specific male’s cytomegalovirus is most efficiently achieved through mouth-to-mouth contact and saliva exchange, particularly where the flow of saliva is from the male to the typically shorter female”.

Back in the 1920s, however, scientists were not aware of this – on the contrary. To avoid the spreading of unwanted germs during kising, they invented the ‘kissing screen’ –  a net on a stick which can be placed between both mouths.

Below the article in which Popular Science promotes this romantic device:
