Ploddalong, if you want to wear jeans and a t-shirt, drive a flash car, have loads of jewelery and pretty women on your arm, then join NATS. Only problem is that you will after a few years crave some variety, but think of the money!
If you want to wear badly cut denim, then join the crabs although as you will not be a member of the two winged master race, you will be a second class citizen. Still travel is good...Anglesey, Scotland, Iraq, Afghanistan, the Falklands, if you are lucky LACC, sat alongside young men with fast cars and women hanging off their arm, or if you are really lucky, Cyprus. Lots of variety, good career prospects (see NATS above) and you could end up doing Area Radar, which will be the most exciting and frightening controlling you will ever do. Plus getting shot at in west London.
Alternatively, you could join the Dark Blue. A small but elegant band with cheap cars and women/men of low voltage hanging off their arms. You could visit all the places above and more. Indeed if you are under 25, you could end up as one of the controllers on HMS Queen Elizabeth

sailing all around the world, a cocktail party in every port, a fine uniform and a large bar bill.
Whatever you choose, you will have made the right decision. I have seen all shades of ATC and they all offer great opportunity, cameraderie and job satisfaction. Remember, it will be two hours of boredom, followed by 2 minutes of utter terror.
