I do not like all this legislating to 'protect' people and children from themselves. I see some schools in america are banning tag in the playground incase someone gets hurt. Children need to play and risk getting scrapped knees etc, and the odd broken bone. It helps them work out in their heads what limits there are. they need to stretch, they need to run around, they need to experiment with finding out what they cannot handle and what they can.
Raising the drinking age has the same affect, there will be no chance for teenagers to find out what they can't and can handle, and do they magically become responsible when they are 20?

I have watched the increase in the nanny state for a while now. Too much legislation. Whatever happened to taking responsiblity for your own actions or stupidity? You got it wrong you learnt. Now we are increasingly taking those life lessons away from teenagers until we 'deem them old enough'. and when they are chronologically old enough what then? They are let loose with few life lessons.
