SLC, on your last point, I am aware of someone TU as unfit.
On the rest of your points, absolutely true. You will have tests to see if you are fit to take the test. The fitness, if mandated, can become boring.
If you are a natural jockstrapper will you be able to do your own thing, running every lunchtime, or will you have to carry sandbags like everyone else?
Will your Saturday football count or will you have to do it on Tuesday, Wednesday and Thursday too?
Will you start work at 7 instead of 8?
If team sport is allowed will you be made to play football when you prefer rugby, larcrosse or hockey?
Is cricket sufficiently physical?
and so on and so on.
PS, my nominated fitness coordinator, soon to be PTL, when he gets back off leave, has been unfit fitness test for over a year.
