Sounds like you need to relax a bit mate. You will not receive enlightenment racing from Tower Bridge to Madame Tussaud's or whatever. Take in a bit of art or some theatre.
Go to Borough Market and eat well. If I were you, I'd get a hotel somewhere pleasant like Hampstead or Bloomsbury (perhaps tubehotels.com/Rookery-58.html) and then just go for roaming days down by the river or on Hampstead Heath. Be sure to sit down if your legs are tired and always to eat something interesting.
There are too many good restaurants in London for anyone to be eating at Pizza Hut or Pret a Manger.
But if that's all the time you have, we want to help you make the most of it by providing a ready-made itinerary that will allow you to have a complete, unforgettable trip. Of course, there is always a hidden London that awaits discovery as you seek out its secret treasures on your own, but that can wait for another day and another trip. You can make the most of your short time by fortifying yourself with an old-fashioned English breakfast -- order "the works," perhaps skipping the blood pudding or sautéed kidneys if you're faint of heart.
That way, if you sleep late (or have a "real tuck-in" as the Brits say), you might even skip lunch, so as not to lose precious daylight hours in your rushed schedule.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
