As sordavie and others have said the study here is a lot more concentrated. I personally prefer the US system, since I still am not sure what the hell I wanna do for the rest of my life and I'm being made to decide right now. However if you have a very specific course in mind then there's nothing wrong with a UK university TBH, so you have to consider the course before anything else.

I'd very much heed Blackdog's advice if you're planning to the USA after your education - you're lucky to have someone like him around that's actually lived it.

The whole traveling and learning aspect is invaluable IMHO, but uni is a full-time commitment for 3 years or so at least depending on the course, so you'll have to think long and hard about if you'll be comfortable moving that far from home for such a long time to an unfamiliar country. Also depends on what university you're looking at. I've had to leanr about this stuff and I can point you to some handy lists of universities in terms of their pass rate (basically how good they are). Also you want to see where it is. Moving to London if you're not in an urban area now, while tying to deal with education can be tough.

It's not as scary as I think I may be making it sound like, but it's a big commitment and you need to think long and hard about it. As an experience, if you decide to take it up, I'm sure it will be eye-opening. It always is. But you have to consider quite a few things before you go gallivanting across the pond and stay in Britain for a number of years.

In terms of your questions on "styles of living", well we have electricity and stuff...The weather's not great, but getting better thanks to global warming. LoL, you'll have to be a little more specific with the questions about life here.
