As a parent of teenagers, I'm all in favour of the higher level of 16, simply because I think there's an educational function to be played there as well. It's not simply a question of strictly consent. It's a question of ensuring that kids under that age are given more opportunities to reflect on what they're doing, what they're consenting to, and what they understand about information collection. There really is an educational role to be played there.
