I think there should be a review of policies at some airlines who ban thier crew from having a walk through the cabin.I think it is essential with this job...it is a very sedentary life.
My average day at a low cost airline involved 12hr duty(sitting)...driving home m25 2hr(sitting)...then straight to bed exhausted (sleeping)...
I'm sure this is what a lot of guys do week to week....not the most active of lifestyles,but maybe this is a wake up call to lead a more active life for some,and policy setting changes for airlines.
