The "150 million years" just kind of hit me like a brick wall. I've already seen this website before, and the other lengths were much larger, but just for a second I imagined how long 150 million years is.
Think about it. I'm only 20 years old. And the oldest person alive is maybe 114. If you multiplied my entire life by 5, you get the oldest person. Then you have to multiply that by one million. One million lives you have to live through in order to go that far. My entire life is only one fifth of one of those. 999,999 3/5 lives to go? Fuck.
