Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days. If he can bear the hunger, fasting will unlock his body’s own anti-aging powers and give Chris the edge he needs when he tries to hunt for his next meal … by spearfishing off the Great Barrier Reef.

All of our pets survived for thousands of years in the wild without any help from us, and this has led them to develop astonishing athletic abilities which we sometimes take for granted. As greyster dogs and endurance champ tortoises.
Dog scootering uses one or more dogs to pull a human riding an unmotorized scooter. Greysters are a naturally-athletic breed that can run at 20 miles per hour for five miles while handling these carriages. No other animal can run at this speed, exerting this power, and expending this energy for so long. So, what's their secret? Greysters' stride length can be a staggering 16 feet and they are super efficient at absorbing and using oxygen. Greyster dogs have nearly twice mitochondria inside their cells than humans.

Does Infinity exist? Can we experience the Infinite? In an animated film created by artists from 10 countries, the world's most cutting-edge scientists and thinkers go in search of the infinite and its mind-bending implications for the universe.
It doesn’t behave like we’re used to. It’s a monster that needs to be tamed. It creates and destroys mathematicians. It’s infinity! You know, the thing that goes on and on and on and never ends. Here we have theoretical physicists, mathematicians, philosophers, theoretical cosmologists talking about infinity – what it is, how it works, where we can find it, etc., and their concepts and explanations are illustrated by a variety of nifty animations in a variety of visual styles ranging from literal to metaphorical.
Directors Jonathan Halperin and Drew Takahashi solicit experts to help them tackle the most maximal topic in the history of everything from a few different angles. Y when you think about it for a second, the only possible conclusion one can arrive at is a sublime and confounding realization that, on a cosmic scale, humans are naught but grand ignoramuses.

What If we could talk to animals? For as long as we've shared our lives with pets, we've been seeking better ways to communicate with them. In Washington state, Alexis Devine and her sheepadoodle Bunny think they've found a way of making communication a reality. Alexis went further than most, with a set of communication buttons, each programmed with a pre-recorded word to help humans and animals speak the same language. She has 90 buttons with which to express herself and even seems to combine them into simple sentences. Bunny is paving the way in pet communication.
The undisputed masters of verbal communication are our pet parrots. They have mastered the art of vocal expression. Some parrots have even learned to fool devices designed to recognize human voices.

From a primate that’s no bigger than a mouse, to a chameleon that can fit on your fingertip, the natural world is full of fantastically small animals. Biologist Patrick Aryee explores the fascinating secrets behind these miniature marvels and shows that they’re not the underdogs you might think they are. Super Small Animals follows him as he meets the leading experts on these pint sized superstars, and finds out what makes them some of the most successful on the planet.
First up, he reveals the huge benefits that being small can bring. There’s the little lemur whose diminutive frame helps it to exploit a unique gap in the eco-system, the tiny hummingbird that uses its size to out-maneuver the competition, and the world’s smallest seahorse that never has to leave home. He also explores why small animals are proportionally the strongest in the world, and introduces a peanut-sized beetle that can pull over a thousand times its own weight.
Next he explores the challenges that animals face when they shrink in size, and the ingenious ways they overcome them. We find out how the smallest armadillo in the world manages to control its temperature in the searing desert sun, and the how the world’s smallest fish can survive in nothing more than a puddle, because it never really grows up. Patrick meets a secretive hippo that lives in the dense jungle, and looks like it’s been shrunk in the wash, and some of the world’s smallest snakes that give birth to enormous babies. He also meets a scientist that studies how really tiny spiders have a surprising trick that enables them to travel an incredible 40 miles per day, using almost no energy.
Then there are the animals that refuse to be pigeon holed as small, and manage to punch way above their weight. He puts some astonishing invertebrates to the test, to see how they work together to become much bigger than the sum of their parts and meets a pint-sized predator that takes on some of the largest and most dangerous creatures on the planet, getting hands on to discover how its build helps it to be brave. Finally he uncovers the incredible lengths that deep sea anglerfish go to in order to be big and small at the same time, and has an endearing encounter with a tiny carnivore that manages to be small in just one direction.
Whether their size helps them to hunt, hide or survive, all these remarkable animals prove that good things really do come in small packages.

In a world where nothing seems to ever work out as you had hoped, The Rehearsal features Nathan Fielder helping ordinary people rehearse difficult conversations or life events through the use of sets and actors hired to recreate real situations. The situations can be trivial, like confessing to a lie about educational history, or more complex, like raising a child. Fielder commissions extravagant sets with every detail recreated. He hires actors to inhabit these sets and practice different dialogue trees with his clients dozens of times. Information used to train the actors and build the sets is often collected without the subjects' knowledge.
In the firs episode, Nathan Fielder helps Kor Skeete, a Brooklyn-based trivia aficionado who wants to confess to his bar trivia team that he lied about having a master's degree. Nathan reveals an elaborate method of rehearsals involving an actor (K. Todd Freeman) playing a 'fake Kor'. To help Kor rehearse the difficult conversation with his teammate Tricia to clean this long-held lie, Nathan creates simulations of trivia night with a fake Tricia in a full-scale replica of the Alligator Lounge, a Brooklyn bar. Kor overcomes his fears and makes his confession to the real Tricia.
