A Silicon Valley Superfood That Makes You 'Bulletproof'

In the late 1990s, Silicon Valley entrepreneur Dave Asprey was overweight and struggling to stay focused. Many adventures and $300,000 later, his "bio-hacking" endeavors eventually led him to create Bulletproof Coffee, a brew he claims gives you steady energy throughout the day and suppresses your appetite for hours. The brew's Tibeten origins proved a unique backdrop to his current business venture of making coffee and life better.
