Moving to Beverley, East Yorkshire............?

Hey....

Well; I'm sure the answer to my questions are already out there, but I can't find them, so..........

Here is my background.

I'm looking to move to Beverley, East Yorkshire.........around the first of 2014.

I'm an American and receive Social Security for my income along with a private retirement fund. 

With this info........

What kind of VISA do I need to get?  Is it hard to get?

And........basically......What do I need to DO or KNOW before I move there?

I'm a 59 yr old male that just wants a nice, quiet, safe place in a village/town - such as Beverley.......to just live out my life there.  I don't care about "partying", etc......I just like to walk myself and dog........read......watch movies......do volunteer work......have a glass or two of wine each night......And just do nothing.......

With this said.............Any info you could give me about moving there and the logistics; I'd truly appreciate it....

And......not having a car; I'd really like to live at the center of town for shopping, etc........And; public transportation is a must.......Other than that; I really don't require much.....
