The guy was deluded.... I don't know many pilots who don't enjoy a keg or three! And I reckon my BMI has been north of 25 since I was about 14 years old!
That's why I do my medicals with the more portly docs....
As for the CDT - been there and got the T-shirt. All I can say is you've got to be a serious lush to get flagged on that...
