#5: A Billion Seconds Is Not Just a Bigger Million
A million and a billion look related on paper, like two cousins wearing the same suit. In real life, they do not behave alike at all. One million seconds adds up to about 11 and a half days, which is long enough for a vacation, a recovery, or a strange week and a half of waiting. One billion seconds stretches to roughly 31.7 years. That is not a slightly larger number. That is a child becoming an adult, a mortgage aging, music styles changing, cars getting redesigned, and whole decades slipping past.
