Title: What Doesn't Kill Us Pdf How Freezing Water, Extreme Altitude and Environmental Conditioning Will Renew Our Lost Evolutionary Strength

What Doesn't Kill Us, a New York Times best seller, traces our evolutionary journey back to a time when survival depended on how well we adapted to the environment around us.

Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our forbears?

Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology? Helping him in his search for the answers is Dutch fitness guru Wim Hof, whose ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Carney also enlists input from an army scientist, a world-famous surfer, the founders of an obstacle course race movement, and ordinary people who have documented how they have cured autoimmune diseases, lost weight, and reversed diabetes. In the process he chronicles his own transformational journey as he pushes his body and mind to the edge of endurance, a quest that culminates in a record-bending 28-hour climb to the snowy peak of Mt. Kilimanjaro wearing nothing but a pair of running shorts and sneakers.

An ambitious blend of investigative reporting and participatory journalism, What Doesn't Kill Us explores the true connection between the mind and the body and reveals the science that allows us to push past our perceived limitations.

I think it has such high reviews because people really like the Wim Hoff method and want something to read ... I was really looking forward to reading this book. But it was a let down. I think it has such high reviews because people really like the Wim Hoff method and want something to read on the topic as there isn't much. I think the subject matter is driving the ratings more than the book itself. But this book hardly has anything to do with the WHM. Basically Scott traveled all over talking to scientist and people that are interested in challenging themselves and their bodies. Problem is the book isn't about what he discovered so much as the story of him traveling and talking to people. Very little information in this book. I don't what to read the life story of every person you talked to. Just tell me what you found out. In particular on the WHM. I was very excited to read about what happened in the WH camp when he went for training in person and the techniques. I think the story about him taking a shower and flooding the house was given more space than anything to actually do with the WHM. I don't care. Also the story about climbing Kilimanjaro was a bit anticlimactic SPOILER ALERT (kind of you already know the ending from the start basically). I thought it was going to be a group of guys that climbed the mountain with just shorts and no shirts in record time. Instead they just took their shirts off sometimes and put them back on when they felt like it. It's still cool that there's some extra cold resistance but it's not the same as climbing the whole mountain shirtless. Also they didn't climb to the top. They just raced up part of it and got close to the top and said we have nothing further to prove once they got tired and said well it's a record to this point. Well I could sprint up the first mile of the trail and collapse and say there I set the record for this point. But nobody's racing to that point. They're pacing themselves to the top.I think the biggest take away was that they climbed the mountain at a faster pace and didn't acclimate to it by using the breathing techniques. I think there's something substantial there. But the climb is a bit hyped up.If you read this expect to read a lot more about Scott entering tough mudders and similar obstacle courses and finishing in the middle of the pack than WM or his methods. Nothing wrong with entering and finishing 53rd. But nobody really wants to read about the guy who did and how he did it. WM is a champion, I want to read about that guy. How does he do it, not how strange he is.If you're looking to learn more about the WHM and techniques to implement just go to youtube. There's nothing new or deeper here. Only one breathing method in the book and it's the same as the one on youtube. Probably about 2 pages of technique in here. The rest is him talking to people and his conversation with Wim Hoff about how he want's to go to Kilmanjaro with him and what a quirky guy Wim is and oh we missed our turn in our blue 2004 chevy van with a rusty bumper and we'll have to turn around probably cost us about 5 maybe 6 minutes to make up for... Seriously about 75% of this book could just be cut out. It's mostly fill and the book knows it. It starts out talking about the end and climbing Kilimanjaro but stops for 15 chapters of fill (maybe 2-3 good ones in there) and holds the rest of the story over your head to keep you reading.Also I got frostbite following the instruction in this book. After reading his story about their first day in camp going out in the cold for 5 minutes in their underwear and rolling in the snow and returning to a sauna. I followed the guidelines in the book and tried it for myself. Basically the story told about how painful it was to stand in the cold for the first time. It's part of the process, how you have to earn your immunity to the cold. Then they came in to the warmth and it was even more painful than the cold. All part of the process. Just have to get through it. There was a chart (page 61) that had on one axis the temperature and the other the wind speed. By connecting the 2 points the chart would tell you how long you can be outside and exposed before getting frostbite. So I rounded down the temperature and rounded up the wind speed to give me a windchill of -17. According to the chart it should take 30 minutes of exposure before frostbite sets in. Although one degree less and it would be in the 10 minute range. A big drop off. But it was day one so I was only doing 5 minutes so I'd be more then fine. Right? So I went out bare foot wearing only some gym shorts and ran around in the snow for 5 minutes. Overall I was just fine but my feet were killing me. But I just reminded myself, it's all part of the process. It's supposed to hurt. And I have a pretty good pain tolerance so I rolled with it. I came inside and as they warmed the pain was almost unbearable. It's all part of the process. I held my feet up to the fire like the guy in the book and took the pain. Well for a short period of time, then it was too much I had to stop that to lay on the floor in agony. I kept waiting and it kept hurting. The next day my feet were still killing me and walking was difficult. I looked up the symptoms of frostbite and it turns out that they are identical to all the symptoms of it's all part of the process. I was peeling dead skin off my feet and toes for a few months. Luckily no permanent damage. I didn't think about it at the time but we had just come out of an extremely cold stretch here in WI where the temp (not windchill) was about -20 to -30 at night. So even though it was 7 out when I did it the ground was still probably -20. So you might want to factor that in prior to trying for yourself. In fact I would have stayed for much longer if it wasn't for my feet hurting so bad as the rest of my body wasn't even cold. Maybe wear some sandals or water shoes or something so you still have the exposure to the air but not the direct contact with the ground. I don't hold this against the book. I was aware of the risk. Although, I think readers should be aware that what he describes as how to know it's working is the exact same as the symptoms of frostbite and it's not working. It's just a question of degree to how much it hurts. Which he describes as a lot, so it's hard to tell. And air temp is not ground temp. But I went back for more with shoes on until my feet healed. So overall the vibe I get from Scott is that he's probably not a bad guy. Seems rather likable. And the book has some tidbits, but it needs some major editing of the delete button kind. I'd much rather read a highly informative pamphlet than a long drawn out book with the same amount of info.Diet, Exercise, and "Winter Yoga!" Got this book for my birthday, and man has it changed how I view health and the human body in general. It always bugged me in the back of my mind how our ancestors managed to get by without air conditioning and hot showers. When I heard about Wim Hof, I instantly knew that he was on to something with his cold tolerance stuff. Seeing him break the world records, go under scientific scrutiny, and even resist an endotoxin and only get a slight headache, I was sold.Before I even got this book I started doing cold showers and saw results within just around 3 days or so. Before, I would take really hot showers and as soon as I got out, the evaporation made me shiver uncontrollably. After doing cold showers (man, did they sting at first!), I'm able to go outside in the snow with no shirt on and it feels more comfortable than what hot showers used to feel like. No shivering, I'm just chill (haha).I also bought Wim Hof's 10 week course for about $190 and can already hold my breath for around 3 minutes without really trying, and I've only been doing these breath exercises for like 3 days. I can do 40 pushups without breathing! I don't need coats and jackets when it's cold outside and my family is complaining and shivering and I'm fine. Just be aware that people can be really resistant to this sort of knowledge because it runs so counter-intuitive to the drug-addicted culture we live in. Prescribed pill popping won't get you healthy, it merely manages different conditions and gives you more side effects than positive results in many cases.Cold tolerance exercises your cardio-vascular system and your immune system and makes it so that your heart has to work less hard to keep you warm and moving. It's also very beneficial for stretching parts of your body that are sore. Just go to Wim Hof's youtube channel and look at all the testimonials of people who have diseases such as Rheumatoid Arthritis, Fibromyalgia, Multiple Sclerosis, even deep skin burns. This stuff really works.So yeah, buy this book and then do it! You can too can become... THE ICEMAN!

Title: Algorithms to Live By Pdf The Computer Science of Human Decisions

A fascinating exploration of how computer algorithms can be applied to our everyday lives, helping to solve common decision-making problems and illuminate the workings of the human mind.

All our lives are constrained by limited space and time, limits that give rise to a particular set of problems. What should we do, or leave undone, in a day or a lifetime? How much messiness should we accept? What balance of new activities and familiar favorites is the most fulfilling? These may seem like uniquely human quandaries, but they are not: computers, too, face the same constraints, so computer scientists have been grappling with their version of such problems for decades. And the solutions they've found have much to teach us.

In a dazzlingly interdisciplinary work, acclaimed author Brian Christian and cognitive scientist Tom Griffiths show how the simple, precise algorithms used by computers can also untangle very human questions. They explain how to have better hunches and when to leave things to chance, how to deal with overwhelming choices and how best to connect with others. From finding a spouse to finding a parking spot, from organizing one's inbox to understanding the workings of human memory, Algorithms to Live By transforms the wisdom of computer science into strategies for human living.

Great book, disagreed with a few points, overall awesome [The original title of this review was: "Great book, though a few inaccuracies & bold claims". See below for two updates on the review and why I changed the title.]I'm a little over halfway with this recently published book, which I'm really enjoying so far - and I expect to enjoy it all the way to the end. A lot of great and unexpected insights here, and it seems that the authors did a good job explaining extremely complex algorithms and showing their applicability to real life (though it's hard for me to tell how good their explanations are to a novice, since I'm an expert in the field - I have two masters in Computer Science and working on my PhD, and was familiar with 90% of the algorithms described before opening the book).My biggest quibble with this book (and the reason they lost a star) is that I noticed a few annoying/sloppy inaccuracies, which makes [made! - see below for updates] me ever so slightly doubt the accuracy and veracity of other areas of the book that I'm less familiar with. The other issue is the boldness of their (otherwise very interesting) conjectures.For example, the authors misunderstand and misquote the 2-minute rule from David Allen's Getting Things Done, claiming the rule tells you to perform any less than 2-min task immediately when it occurs to you - and essentially simplifying the entire GTD system into the 2-min rule, which is in fact a tiny part of GTD (pg. 105-106). In fact, however, Allen does not suggest that at all - that would distract you from whatever you're currently engaged with, i.e. require a context switch (the costs of which the authors discuss at length). Instead, you should write that task down and add it to your intray, just like any other task. The 2-minute rule is applied later, while clearing your intray (which can be anytime in the next 48 hours). The point of the 2-minute rule is that the time spent on adding this task into your otherwise-extremely-flexible GTD system, and then tracking it in said system, would take longer than two minutes. This type of tracking is akin to what the authors refer to as "meta-work", and thus performing the 2-min task at inbox clearing time saves you an equal or greater amount of meta-work later. This is completely in line with the type of scheduling suggestions that the authors discuss. I'm not familiar with the other popular advice books the authors quote in the scheduling chapter or in the others chapters (e.g. the empty-your-closet type books they discuss in chapter 4), so I don't know if there are other such mischaracterizations, but it makes me suspect there might be. And I get that they're trying to differentiate their own advice from "all the other pop books out there", but if they're going to explicitly cite other books, they should try not to misrepresent them.Also, when discussing the Gittins rule and the multi-armed bandit problem, they say that a machine with a 0-0 record has "a Gittins index of 0.7029. In other words, something you have no experience with whatsoever is more attractive than a machine that you know pays out seven times out of ten!" (pg. 40). However, their own table on the same page clearly shows that a machine with a 7-3 record has a Gittins index of 0.7187, making such a machine ever so slightly superior to a 0-0 one. After some more reading I realized that what they meant was that a machine with a 0-0 record and *uncertainty* is better than a *certain payout* of 70% (i.e. guaranteed to payout 7 out of 10), but that was not what the text implied.To be clear, these inaccuracies in and of themselves aren't huge - but they planted a seed of doubt in my mind [which is not as big anymore - see below] as to whether there were other such misrepresentations or inaccuracies in the book that I simply hadn't caught, and detracted from my enjoyment of the book.The other concern I have with this book is that several chapters end with provocative suggestions that aren't actually empirically-backed. These conjectures are cool, but I'd have liked to see scientists be more careful about making such bold claims, or at least couching them in the need for more research to establish whether they were entirely true. One example here was the discussion about the decline of aging supposedly being a result of simply having a larger history to remember (pgs 103-104). This is a fascinating conjecture, and one that deserves to be studied properly, but they are basing it on some research work that was not age-related. I suspect the authors may be on to something, at least in the context of "normal aging" cognitive decline as opposed to, say, alzheimer-related decline. However, as stated in the text, the conjectures are stated a bit too strongly for my tastes ("But as you age, and begin to experience these sporadic latencies, take heart: the length of the delay is partly an indicator of the extent of your experience.", pg 104). I'd hate to see anyone making decisions based on them - potentially missing an earlier diagnosis, say, of alzheimer's, because the authors claimed that cognitive decline is totally normal.Quibbles and concerns notwithstanding, I'm definitely enjoying the book and I think it's a great addition to the new genre of what's being called by some "science-help". It's also a good read for people who are tired of the same-old, and thirsty for some advice that's off the beaten path.UPDATE:The rest of the book was as good as I expected.Additionally, I sent this review to the lead author (Brian Christian) in case he wanted to address these issues. I was delighted to receive a very thoughtful response from him! They will be fixing the Gittens rule description in the paperback edition, to make it clearer to the reader. The author respectfully disagreed with me on the other two issues (GTD 2 minute rule & cognitive decline).Given what I saw in the email, I'd say the intentions behind the book definitely merit 5 stars (even though I still disagree on their presentation of those two topics). However, I'll leave the original title & rating of 4 stars as it stands for the original hardcover edition, and for consistency's sake. As I originally said, the book stands as an excellent addition to the genre, and also likely as a great first exposure into Computer Science if you've never had any.2nd update:Apparently, this review is now listed as the top most helpful review on Amazon (cool!). The book has been so successful that the first author (Brian Christian) recently informed me that the book is now on its third printing, which means that the Gittins index issue mentioned above is now fixed in the current and future editions. As for the other issues I had, they are more subjective in nature, and not large enough in and of themselves to merit the original (harsher) title of the review. Again, for completeness' sake and to avoid rewriting history, I leave the original review as its stands and the original title is listed below the new title, with only a few comments in brackets leading readers to these updates in the bottom.
