Dont worry it is tempered with common sense! Had a great season as prop for the Fleet air arm, only next aircrew medical I was declared 35% overweight. The doc said I had to lose weight, I replied -up your bum chumpy, Ive got selection for the RN team in 2 months time! Long and the short of it was had to do a body fat analysis and a VO2 uptake test which showed I was fitter and leaner than average. Now got a great 'get out of jail free chit' in my medical docs for future years!!!
