Now that the great British pound is nudging two dollars, calculating how much things cost has become really easy. I still find it hard to think in dollar terms and perform the calculation frequently.
There are other factors of two in my financial life. I get paid twice a month, and I've noticed that a lot of things in America seem to be roughly half price (however it should be noted that rent definitely does not fall into this category).
So, I get paid in a currency that in numeric terms is twice the UK figure, I get paid twice as often, and consumer goods can often be considered half price.
I certainly feel better off, even if I'm probably not. God bless America.
