The BMI boll*cks system doesn't take into account frame size and bone structure - even a nurse can tell you that
My first aircrew medical at Biggin Hill, (circa 1970) the Doc had his own assessment chart
Right at the top was "physical appearance" - this was his 1st impression when you appeared in your shreddies
If you satisfied this initial check, the rest of the exam was easy peasy - vital signs etc, blah
Obviosly someone who knew his job based on his experience and not bound by PC cr*p and government targets
My BMI is at the lower end (24?) but is still less than the BMI of Carol Vorderman's arse!
