I'm sure if one of them does retire, they could recommend someone else.
We tried that with Kevin, the guy who built our garage. The only person he was prepared to recommend was even older than he was! Vaughn the digger driver is another. He's an absolute whizz with a mini digger, he's as precise as a surgeon wielding a scalpel, but the poor bugger is so old now we have to help him on and off, bless him.
