A lot of interesting stuff happened during his four years. The Mexican-American war, the US and UK coming to a settlement over Oregon Territory, Texas joining the union, the forced purchase of New Mexico and California, the political unrest between the north and south... The guy wore himself out and died shortly after returning to Tennessee.
I'm really surprised he wasn't more prominent in the history books I read in school.
I had a guy from Florida tell me that the oil wells just fill up again after you empty them, so the whole oil shortage is a scam.
I mean, they do, for a while anyway... but it's like that last little bit of a milkshake that you never quite get through a straw. There's no new oil - it's just the stuff that is just now making it into the well. He thought you just waited a handful of years and you'd have another gusher.
