Bloody hell, what is wrong with you lot?
I thought heavy duty machines only for over 70s.
I used to work in a community clinic with a very camp chiropidist. Waiting room would be full of little kids waiting to see me (salt) and oldies waiting to see him. He would mince out and order them all to remove shoes and hosiery before entering. And they did.
Would be rows of 'em with bare feet.
