True. The ‘2m rule’ came out before we knew COVID was airborne. . . itself an interesting story based on information on particle size being wrongly interpreted decades ago..imho the 2m rule is a bit BS, thats really close. but it probably doesn't matter as it stays in the air for people to breath in. hence why mask use is so important.
My somewhat facetious take on it is if you can *see* someone outside your bubble without a mask. . . you’re too close !
