Just as well that it is only the friends of PPRuNers that have these health concerns!
I have not been able to confirm this but it was stated on here a few weeks ago that a Body Mass Index of greater than 35 would be a problem.
To calculate your (friends) BMI apply the following formula:
BMI = weight (kg) / (height (m) *height (m))
So if we take 104/3.35 we get a BMI of 31 which means too fat but should be OK for the medical.
