Six Foot Distancing Rule Is A Made Up Number

Social Distancing at 6 feet is the new gospel in Canada and the United States.  The number is a by-guess-and-by-gosh contraption and not the result of research.
Have a look at this chart for other countries with the 2 metre rule,the 1.5 metre rule and the 1 metre rule.  Different strokes for different folks but the same virus.

Just to be picky, the six foot rule is a 1.82 metre rule.

UPDATE: The Daily Mail weighs in May 20th.  The science for 2 metres is missing and  Australia has the 1 metre rule which makes it much easier for restaurants to open.
