As a real doctor and an engineer I realised many years ago that I'd sure hit on a losing combination! But Flyingmac is right: life is too short. Nevertheless, I still have a chuckle when I see a 100 hour recreational pilot emerge from the latest plastic fantastic wearing a pressed flying suit with a glory of insignia. You'd like to think it's a phase but some of them look disturbingly middle aged. But to each his own.
