#743: Dr. Jane Goodall and Cal Fussman

episode is brought to you by 8 Sleep. I have been using 8 Sleep pod cover for years now. Why? Well, by simply adding it to your existing mattress on top, like a fitted sheet, you can automatically cool down or warm up each side of your bed. 8 Sleep recently launched their newest generation of the pod, and I'm excited to test it out, Pod 4 Ultra. It cools, it heats, and now it elevates automatically. More on that in a second. First, Pod 4 Ultra can cool down each side of the bed as much as 20 degrees Fahrenheit below room temperature, keeping you and your partner cool even in a heat wave, or you can switch it up depending on which of you is heat sensitive. I am always more heat sensitive, pulling the sheets off, closing the windows, trying to crank the AC down. This solves all of that. Pod 4 Ultra also introduces an adjustable base that fits between your mattress and your bed frame and adds reading and sleeping positions for the best unwinding experience. For those snore heavy nights, the pod can detect your snoring and automatically lift your head by a few degrees to improve air flow and stop you or your partner from snoring. Plus, with the Pod 4 Ultra, you can leave your wearables on the nightstand. You won't need them because these types of metrics are integrated into the Pod 4 Ultra itself. They have imperceptible sensors which track your sleep time, sleep bases, and HRV. Their heart rate tracking, as just one example, is at 99% accuracy. So get your best night's sleep. Head to 8sleep.com/tim and use code Tim to get $350 off of the Pod 4 Ultra. That's 8sleep, all spelled out, 8sleep.com/tim, and code Tim, T-I-M, to get $350 off the Pod 4 Ultra. They currently ship to the United States, Canada, the United Kingdom, Europe, and Australia.

This episode is brought to you by Mementis.

Mementis offers high-quality supplements and products across a broad spectrum of categories, including sports performance, sleep, cognitive health, hormone support, and more. I've been testing their products for months now and I have a few that I use constantly. One of the things I love about Mementis is that they offer many single ingredient and third-party tested formulations. I'll come back to the latter part of that a little bit later. Personally, I've been using Mementis Mag3N8, L-Theanine, and Apigenin, all of which have helped me to improve the onset quality and duration of my sleep. Now, the Mementis Sleep Pack conveniently delivers single servings of all three of these ingredients. I've also been using Mementis Creatine, which doesn't just help for physical performance, but also for cognitive performance. In fact, I've been taking it daily, typically before podcast recording, as there are various studies and reviews and meta-analyses pointing to improvements in short-term memory and performance under stress. So those are some of the products that I've been using very consistently. And to give you an idea, I'm packing right now for an international trip. I tend to be very minimalist and I'm taking these with me nonetheless.

Now back to the bigger picture. Olympians, Tour de France winners, Tour de France winners, the US military and more than 175 college and professional sports teams rely on Mementis and their products. Mementis also partners with some of the best minds in human performance to bring world-class products to market, including a few you will recognize from this podcast, like Dr. Andrew Huberman and Dr. Kelly Starratt. They also work with Dr. Stacey Sims, who assist Mementis in developing products specifically for women. Their products contain high-quality ingredients that are third-party tested, which in this case means informed sport and or NSF certified, so you can trust that what is on the label is in the bottle and nothing else.

And trust me, as someone who knows the sports nutrition and supplement world very well, that is a differentiator that you want in anything that you consume in this entire sector. So good news. For my non-US listeners, more good news, not to worry, Mementis ships internationally, so you have the same access that I do. So check it out.

Hello boys and girls, ladies and germs. This is Tim Ferris. Welcome to another episode of The Tim Ferris Show, where it is my job to sit down with world-class performers from every field imaginable to tease out the habits, routines, favorite books, and so on that you can apply and test in your own lives.

This episode is a two-for-one, and that's because the podcast recently hit its 10th year anniversary, which is insane to think about, and passed one billion downloads. To celebrate, I've curated some of the best of the best, some of my favorites from more than 700 episodes over the last decade.
