Cloud computing pioneer Dave Asprey took a trip to Tibet in 2004 to learn how to meditate. But it was the yak-butter tea he tried there that ended up transforming his life.
“I had so much more energy and I didn’t feel sick at the altitude at all. I realized: There’s something going on here. I just felt so good, I’d never go back to a coffee maker with grinder combination” he remembers. He returned home and spent several years fiddling with ingredients, aiming for “a hot version of a Frappuccino without the milk and sugar.” He started with a base of coffee instead of tea because he’s an aficionado; he says he got his only undergraduate “A” the semester he discovered espresso. And the ban on milk and sugar was one of the many biohacks he had practiced over 15 years (and $300,000 in doctors and 3-D radioactive scans of his brain metabolism) trying to rid himself of “brain fog” and 100 pounds of extra weight.
