Looks like the government ( uk) are considering reducing the 2m rule to 1.5 ...
Most people over 60 don’t even know how long a metre is in the first place ! !
When I’m asked how long two metres is I tell them it’s the same as the height of a door .
Anyways I don’t like the idea of reducing the distance given that research showing the particles can travel 13’ ( 4 metres) when airborne ! !
