Height is indeed extremely relevant in this thread. For instance, if people were aware that my wife was constantly vigilant about the calorific value of every morsel of food she eats and yet weighs less than six and a half stones, you'd probably assume she was anorexic but she most certainly isn't. She had never weighed more than six stones in her entire life unless she was carrying either of our two boys but since her job became more sedentary (off the wards and into the office), she was as depressed at hitting six and a half stones as she would have been if she'd been told she had to have a leg amputated. But height-wise, she is in perfect proportion.
