One of the best things that happened to me was the first time someone called me a quack.

If a quack's like a duck, is it a duck? Or is this just the future, waddling into sight?

It's note to self, the tech show about being human. I'm Anouche Summerodi.

Today, going to extremes in the name of optimizing your mind, your body, your life.

It's a conversation with Dave Asprey, Silicon Valley entrepreneur who wants you to start your day

with buttered coffee or bulletproof coffee as he calls it. Maybe you've heard of it,

maybe you've heard of him. Every time your brain does something you don't want to, you tell a

shut up and eventually gets out of its own way and you're like, okay, hold on, like, like,

you know, stuff's happening. I don't have arms right now.

That was a clip from his podcast, The Bulletproof Executive, which is part of his bulletproof

empire. There's the coffee, the book, the diet, the blog. It's tagline. A state of high performance.

But what makes him different than any other health fitness business guru out there?

Well, he's got a twist of Silicon Valley in him. In fact, he runs something called the Silicon

Valley Health Institute. He's a particular brand of guru who relies on data and sees his body as

something to be experimented with, kind of like Tim Ferris. Maybe you know him, he's been known

to weigh his own feces, or Josh Witten, who donates blood as often as the Red Cross will let him

to keep his ferritin levels down. If you aren't familiar with these guys, I'm guessing you think

this sounds kind of ridiculous. Self-centered biohackers, you should get a life, right? Yeah, but if

you've ever listened to this show, you know I love me some self-experimentation. Because I do want

to live my best and longest life possible. Because I like feeling good and sharp, in body and mind.

And yes, because maybe I am part robot. Frankly, really though, not a lot of women weigh in on what these

guys talk about. So... They're about half of us process light differently than others.
