Whoa, that's a tough one.
Throughout the last decade in particular, we have tried to figure out "who is next?", but time and time again we are overtaken by someone who suddenly comes in from the sidelines and takes it all, whether it was a ski jumper, a soccer player or a fish factory employee (or latest this home trainer guy).
So I dare not put a tick among the well-known suspects in the list.
So perhaps it was more relevant to guess whether the next person who suddenly pops up in the sky is a sanitation worker, a magician, a butcher or a fired bank clerk who has had to flee to other pastures to earn a living?
