I'm legal yet old

OK, so today I turned 18. Yeah I know, it makes us feel old. Now i'm free! Well, not just yet, well according to my laws of legality:

When you turn.... You're legally allowed to.....
16 have sex, play the lottery;
17 drive;
18 be legal in the UK and some US states, drink alcohol (UK, not US);
19 be legally allowed to be a teen for the last time;
20 be legally allowed to be in your twenties for the first time;
21 be legal globally.

Now how's that!? Oh and before I forget, I share the same birthday with Elton John, Arethra Franklin and Marcia Cross (Bree from Desperate Housewives). This is a pointless blog isn't it? Oh well, I felt like it!
