I noticed the preponderance of Northerners (as a Northerner myself) and wondered if it was anything to do with travelling restrictions resulting from COVID.
On a slightly related note, Pointless seems to have a HUGE proportion of people who are actors./ directors/ playwrites etc this at the moment, and I wondered if they were similarly restricted - they have an even greater turnover of contestants.
During ordinary times, though, I'd like ordinary people - I don't mind what race, colour or creed or sex they are, but I don't need them necessarily to have a collection of earwax or to train goldfish to jump through hoops in their bathtub.
Just good, pleasan,t craftspeople skilled in whatever field they have entered for.
