we’ll have little drive or purpose, work will seem futile, we’ll become paranoid about people being after our money, we’ll need security, we’ll have to hide out, on the other hand, we can play a lot of chess. And devote pretty much all of our time to intensive strength training.
however, if the money really necessary? i just bought the “chesster” kids software and a really nice wood chess set (discounted) from http://www.houseofstaunton.com all for under $100.00….; doubt 500 million would get us a much nicer set or add very much to our happiness.
