This week, FW and I had a very long discussion about inventions and what were the most life changing of all inventions. We basically limited our discussion to the past 50 years or so and agreed upon The Pill and The Internet as the two biggest ones. I also argued for drive through liquor stores, but we couldn't agree on that. I say that anytime you don't actually have to get out of your car to buy something is a good thing. Look at fast food places. Who actually goes in anymore? Anyway, you don't have to limit yourself to the past 50 years, and you don't have to limit yourself to life changing inventions. You could simply say what is the one invention you cannot live without.
