The world's richest man, Bill Gates, can do a heck of a whole lot with his $72 billion worth.

1. The Richest Man In the World

Gates was in No. 1 position on the Forbes list from 1995 to 2007 and again in 2009. On May 16 Bloomberg announced that Bill Gates was back on top with an estimated net worth of $72.7 billion.

2. He is One Of the Richest Countries In the World, Too

If Bill Gates were a country, he would be the 37th richest country on earth.

3. He Knew He'd Be Filthy Rich

In school he bragged to his teachers that he would be a millionaire by the time he was 30; he was a billionaire by 31.

4. It's Literally Not Worth His Time to Pick Up a Dropped $100 Bill From the Ground

With a worth of $72 billion, a 6% rate of return would earn Gates roughly $114.16 per second he is alive, making it a poor investment for Bill Gates to bother picking up a $100 bill if he dropped it.

5. He's a Big Spender

Bill Gates has donated more than $26 billion dollars to philanthropic causes through the Bill & Melinda Gates Foundation. That includes $10 billion for vaccine research over the next ten years.

6. His First Big Sale

Bill Gates’ first computer program sale was at 17 for $4,200. He sold a time-tabling system to his high school. Not too bad for a start.

7. What It Would Take For Him to Lose Everything

Bill Gates is 57 this year. If we assume that he will live for another 33 years, he has to spend $6 million per day to use up all of his wealth.

8. He Can Give Everyone On Earth $10 and Still Be Loaded

If he gave everyone on Earth $10 this Christmas, he’d still have $2.26 billion left.

9. His Kids Aren't Loaded

Gates is only going to give a minuscule amount to his kids. “I don’t think that amount of money would be good for them. They have to find their own way. They will be given an unbelievable education and that will all be paid for. And certainly anything related to health issues we will take care of. But in terms of their income, they will have to pick a job they like and go to work,” Gates said.

10. Frozen Assets

If Microsoft Windows’ users could claim $1 for every time their Microsoft Windows freezes, Bill Gates would be bankrupt in about three days!
