Hi from SmithAir747, a former London resident!
I spent the last 3 years (2004-2007) in London, studying at King's College London. And these were the best 3 years of my life so far.
You will really enjoy London. I consider my experience in London to have been the most valuable experience I've had in my life so far.
Be warned, once you get your first taste of London, it stays with you forever and you never want to leave London again. That happened to me. I grew to love London so much (and the people I met there), that when it came time for me to leave London in June 2007 (to move to San Francisco to start my PhD at UCSF). I really had a difficult time saying goodbye and leaving London.
Although my obvious reason for being in London for 3 years was my studies at King's College London (in craniofacial sciences), I learned so much more outside the university than in it. I met so many interesting people, many of whom became my closest friends (some even became "family" to me), both within the College and out in the city itself. For example, these include fellow students and professors at KCL, a few of my fellow spotters at LHR
(a regular weekend haunt for me), several vendors along Portobello Road who supplied me with antique medical devices and Soviet surplus, and especially my church family at American Church in London and my "harem" of ladies who took me under their wing. By the time I finished in June 2007, I had a large "family" in London! It was hard to say goodbye to everyone there as I was coming back home to the USA.
London has so much to do, so much history, so much personality. London has something for everyone, including me--who loves antique medical instruments (London is full of medical and anatomical museums). Whatever your taste is, London will satisfy it.
You could take me out of London, but nobody could ever take London out of me. It's part of my alien DNA now! Someday, I hope there is an opportunity for me to move back to London! If there is ever the opportunity for me to continue my research in craniofacial embryology in London again, I will jump at it!
I will praise thee; for I am fearfully and wonderfully made... (Psalm 139:14)
