I've wondered about that.

I remember seeing a Mythbusters about sneezing and coughing, and my kids watched an Operation Ouch on the same subject (spraying paint, IIRC), and coughs/sneezes travel much much further than two metres.

I also remember the QI demonstration with the vomiting mannequin, although that's not quite the same thing.

It’s funny that we are being told to distance by 6ft, whereas the WHO say 3 feet is adequate.

3 ft each?

I know, but found it interesting that none of the many listed authors on the site were willing to put their names on that article. As I understand it, that advice went beyond the science then as now.

3ft is hardly distancing. We should give people that much space anyway.

No, that’s where the confusion has created the unnecessarily large distancing. Imagine you have a 3 ft diameter disc and you are positioned in the centre. The distance you need to maintain is from where the edge of your disc touches the next person, not where the edge of your disc meets the edge of their disc ( which is what’s being done ). The gap is twice as large as it needs to be, which is important if you find yourself queuing somewhere ( outside a supermarket for example). The queue would move quicker, and things would be easier if the mis understanding wasn’t there.

Can those people actually get wipes anywhere? I've not looked at the gel/wipes sections in supermarkets but I've guessed that they will probably be like toilet paper shelves (empty). So if you can't buy them you can't use them through no fault of those individuals.

Fair enough, as I had a look in the supermarket this morning and there were none to be found.
However, it simply appeared as if none of them had even considered the possibility of having some form of protection.

As an aside, in Morrisons this morning, they had an operative wiping down the trolley handles in between customers.
Tesco on the other hand, didn't.

I'm lucky that where I live is surrounded by a lot of countryside and quiet roads so safe distance cycling is usually the norm.
Sunday was,as expected,quite busy but distancing wasn't an issue.
I did see 4 riders wheel to wheel climbing out of Holmfirth but that's up to them I suppose.

On Saturday they had a poor wee lass inside my tesco offering to wipe down handles. I told her it was probably a waste of time unless I then washed my hands before touching it again. Seeing as shoppers are restricted, then not as many baskets and trolleys are needed, so an operative could collect used ones, clean them then return them to a pile of cleaned ones for customers to use

edition: yep - after I had collected it from outside, and entered the shop...

How do you figure that? It's not completely effective but it's probably better than time-wasting. Oh wait, do you mean they were offering to wipe them after you'd picked them up? That's just bonkers

There are reports of some shops regulating the number of shoppers by only deploying N trollies and every shopper must have a trolley.
