What a stupid statement to make......
Not at all; it's entirely logical and reasoned.
I have been doing the fitness test since it was introduced in 1993. That's quite a few. Of those Ive watched wait behind as I left, most seemed to be in their 20's.
Your experience may be different, but I assure you from discussions in the crewroom, many seem to have shared my experience of watching a fairish percentage of 20 somethings fail.
Of those, many are unlikely to have passed Sandhurst, pre-para and P Coy as the CDS will have done in his youth.
So which bit of the statement is stupid?
