While we’re on the topic of life expectancy, Tim Urban of Wait But Why used a simplified estimate of average life span and then extrapolated for various events in one’s life.
For example, Urban is 34 years old, so that number of Super Bowls has passed. Then assume a 90-year life span, and you have the number of Super Bowls left in his lifetime. Other extrapolations include winters left set in snow flakes, dumplings to eat set in a dumpling emoji, and time left with parents set with stick figure icons.
The math is simple, and you can easily do it in your head, but somehow seeing it as icons has a more sensitive effect. [Thanks, David]
