Tim Urban has created a wonderful series of infographics over at "Wait But Why."
The graphics illustrate "your life in weeks."
If you're an American male and you make it to the average life expectancy of just over 76 years, you'll live about 3,962 weeks.
If you're a American female, you'll probably live longer - about 81 and a quarter years, or 4,225 weeks.
Either way, it's startling to see all those weeks laid out in a single chart. And it's sobering to see how relatively few of them you probably have left.
Here, for example, is Urban's chart of the "life of the typical American."
Each row is a year. Each dot in each row is a week.
The colors show the basic periods in the typical life.
Holy crap! If I live an average life span for my gender, I only have another 1,404 weeks!
