Hey, it's Ben Greenfield. I just emerged from five days immersed in a wilderness survival

program with my children. And needless to say, I was completely unplugged and didn't

do much podcasting during that time. So in lieu of today's normal podcast, I'm releasing

a special interview with the one and only Tim Ferris. Now, before we get on to that interview,

just a couple of things. First of all, if you're curious about what wilderness survival

camp I was at, go Google the Twin Eagles school, the Twin Eagles school. It's up by

sand point Idaho. It was an amazing experience that I highly recommend, although I am incredibly

scruffy and look like grizzly bear atoms right now. So the next thing is that this podcast

is actually brought to you by Casper mattresses, which I truly appreciate having not slept

on a mattress for the better part of the past week. So what are Casper mattresses? Well,

they're quite unique. They're this new hybrid mattress. I've got one in one of the rooms

in my house. And they're incredibly soft because they combine premium latex foam with

memory foam. But what they've also done, and this might perk up your ears, is they've

cut the cost of dealing with resellers and showrooms. And they've passed that savings

directly on to you. So you can get one of these premium healthy mattresses for a fraction

of the price. So it's obsessively engineered. It has just the right sink. It has just the

right bounce. And here's where you can get a Casper mattress with a risk free trial and

a risk free return policy, meaning that you can sleep on it for a hundred days and just

send it back if you don't like it. So the URL is Casper.com slash Ben and just use promo code

Ben there and you'll get $50 off towards any mattress purchase. That's Casper.com slash Ben

with promo code Ben easy enough. Okay. Now onto today's episode with Tim Ferris in this episode

of the Ben Greenfield Fitness Podcast. It is long as you manage your sodium and potassium and so on.
