I am planning to move to London once I retire!
That sounds fabulous!  I adore London and have been there a few times since my brother-in-law is from there. He always calls it "Londinium" because thats what the Romans called it.
I had no idea, that is interesting!  What is your favorite thing to see in London?
I know this is fairly generic but I love to see Big Ben, that gorgeous clock!  Its amazing! But London really does have art, entertainment, fashion, and so much more for tourism. What do you hope to see first once you're there?
I really love to just ride my bike and enjoy the city, oh and get some great things to eat!
You'll never be bored or lack people to meet and talk to since its the most-visited city measured by international arrivals and has the world's largest city airport. I would hope so with everyone coming there to visit or live! Oh, I do love British curry dishes!
Which airport is the world's largest?  That sounds quite overwhelming!
London does. Its really more of the city airport system and they measured passenger traffic from the airport. It topped every other airport in the entire world!  It is the city out of all of England that has the most people so you might want to live a bit out of the city if you don't prefer too many people.
