Bill Gates vs. Mark Zuckerberg

When Gates was a kid, he spent so much time reading that his parents finally forbade him from bringing books to the dinner table. Gates took a break from classes his senior year in high school to do programming with his friend Paul Allen at a power plant in North Bonneville, Washington.

Zuckerberg and his wife, Priscilla Chan, are spending $3 billion in an attempt to end, cure or manage all disease by the year 2100. In January 2019, Mark Zuckerberg purchased $59 million worth of waterfront property on Lake Tahoe in California.
