FLR,
Congrats on your new position with BA. Solid argument from your point of view. Health is critically important in our line of work. I have also heard that years of long-haul flying can be detrimental to one's health and relationships (i.e., missing children as they grow up and experiencing spousal challenges). I know Virgin and BA pilots who seem to be exhausted by frequent long-haul, multi-time zone trips (no big surprise with that type of flying). At least they can sometimes relax at the beach down route. Valid points all around.
I guess you cannot win in this flying job - both long-haul and short-haul flying can reduce your lifespan...
Time to get a law degree!
