In the case of Rod Anyan, who was a boarder with me in Pridham House in the Sixties, a career in flying finally led to the ownership of his own resort on on the Southern West (Atlantic) Coast of Portugal.
Casas Buganvilia Resort looks a wonderful, eco-friendly place and judging by the reviews and photos in TripAdvisor he will have many repeat visitors.
If I'm ever in Portugal on holiday I'll head that way myself.
