British logic

Is there like a law to the first set or something?

Well in the UK's defense (because no one asked) sex is natural and healthy but porn isn't always exactly the best place to learn about sex hence the restriction on the sale of porn. There is no restriction on the supply of health/family planning advice to under 18 year olds, I think they just don't want you watching stuff and thinking that's normal. You can join the army at 16 and get your army groove on but you will not be allowed to be sent into a combat zone or take part in a combat role and see people blown up and shot until you're 18 - just like the video game restriction (which we all comply with right kids?). The cigarettes one they're just trying to stop people smoking because of the health thing but it's not actually illegal to smoke if you're 16 or under as there's no law about age and smoking except the actual sale and supply of tobacco.

no age restrictions for drinking tea!

Hah zombiestitcher has a good point if only when there are offensive jokes about America people would actually defend themselves like that instead of taking it.

And now you see why we Americans left you people!
