Ok, I know I'm only just out of my teens at 20/21 but I feel that this gives ME the best insight into your problems....(sorry I was a psyc student for 2 years)...ok here's the answers to your questions:

1)it is impossible to stop a teenager from eating pizza constantly, one way to stop this though, is to tell him if he wants pizza he can buy it himself get pocket money, or you buy it and he gets no pocket money. Bribery is always the bast way with teenagers as £/$ signs are always rolling around their eyes, just like in cartoons. If he does stop eating the pizza he will do what your next question was....

2) He will keep going back to the fridge every 30 seconds or so to see if anything "decent" to eat has appeared in the fridge ie: chokkie bikkies, chocolate....or cold pizza.....

3)a, b, c and d!!!!

4) a, but you don't really have to worry about his pulse, we are usually just mesmorised by the music, so that's not a problem. NEVER, I repeat NEVER send a teenager out into sunlight, we are all VAMPIRES!! So never open the bedroom curtains ever!!

5)yes, except for the underwear part. EWWWWW!! Girls are obviously much more hygienic!!

Some other pointers.....never tell him he needs to shave even when he decideds it'd be cool to have a beard. This only encourages them!!

ONE GOLDEN RULE: WHATEVER THEY LIKE YOU MUST HATE, AND WHATEVER YOU LIKE THEY HATE!!

I know i did it with folk music for 18 years!! I've learned from my mistake though!!

Yes I know this rule sounds totally stupid, but it will help in the long run. If you want to have something in common, let him say he likes it too first...then you know you're in and you can start liking the same stuff, but not everything, I mean, that would just be wierd...........................................................................................
