He lives on a rural farm in Ireland or Scotland and is involved in a simple, 1800's way of living with minimal technology.He hasn't done a role since 2017, it's been around 5 years now. I'm leaning towards he's done, he's a man of his word. But I hope he does change his mind.
Although I wonder what keeps him occupied. I'm pretty sure he likes building things, he's very good with his hands. Maybe that's what he does.
