Much as I kind of like the idea behind this (dementia links, kids are still developing etc etc and it probably isn't that good for them) the ability to head a ball is a key part of the game and 12 is probably a bit too old to learn how to head.
Also, if English kids are banned from heading until 12 but other countries don't do the same, in 10-15 years how is this going to affect national/club sides?
