But don't hug granny ..lmao..Granny and gramps ( especially in their eighties and nineties )usually dont have great health.Do people forget elderly people before covid died regularly from pneumonia or the flu.Why do we have borders ? To keep as much as the illegal goods,drugs,weapons etc out as possible..these lateral flow kits are much like that ,they wont catch everything but they will reduce the spread.In their world its let's do nothing and see how that goes and lets not offer up their brilliant solution.
