Science & Mathematics - 20 February 2007

I am 35-years-old and in relatively good health. I've always drank some iced tea each morning and sometimes in the afternoon. Since I started taking Synthroid, I noticed chest pains and tachycardia (fast heart beat) on days that I drink caffeine. Since I have quit caffeine cold-turkey several days ago, the chest pains and tachycardia have completely disappeared. Could there be a connection there?

Someone asked me a strange question, How many cities are in the USA? And i want to know how many cities are in England?
What's the difference between England, and the UK? Because someone says England and some UK? Why?

We call the people from England as english, Britons, or british?
I get very confused about these questions~
Can anyone solve my question?
