I've had a few friends receive these letters recently and the reaction is broadly the same:
"What a load of bollocks"
"He/she is always moving"
"There's not an ounce of fat on him/her"
I was prompted to start this thread as a friend has recently posted a pic of her DC's letter on Facebook. Cue many comments along the lines of the above statements.
My AIBU is, what's the point spending the money to print and post these letters when most (in my admittedly limited experience as perhaps those that do act on it are less outspoken) parents declare them nonsense anyway.
Would it be better to save the money and spend it on better physical education in schools or something?
