I don't even look at the prices when I fill up. It's not that I'm fabulously wealthy....but rather why stress about something I really cannot control. I can walk or ride my bike, I guess, but where's the fun in that?
If I recall correctly, last time I looked at the cost of gas here in the Bay Area, it was:
87: Plasma,
89: Blood,
91: Kidney
Or something like that.
