Years ago on exchange I had to book a fitness test with my parent unit 2 hours' drive away. The corporal asked me what I did to keep fit and I said that I played rugby for a local team. Turns out he played too and our stations met in the RAF cup the year before. "I was the skinny bugger on the right wing," I said. "Ah yes, I remember you," he said. "Well if you can do that, you can pass your fitness test. Don't bother coming down I'll sign you off!" No sign of empire building there and a good helping of common sense!
