  1. It's also pretty inefficient though. I bet when post-humans of the future start designing their bodies, the first thing they'd do is make a circulatory system that doesn't rely on a single oh-so-fragile pump.

  2. 14:46 "Rogue Like?" At first I was like, maybe this video will show me some amazing thing that I didn't know about before. But nope. Haha. He's just basically describing games in very general terms from a non-gamer's perspective, and realizing how deep games can be. 😅

  3. "kala" means "black" in Sanskrit. So all in all, "kala kala kala" means "good black fish".

  5.  @GhostofTrufflePast  Just because biomimetics exist doesn't mean evolution always has an optimal result. Just look at all the dead ends that came before us. Or the fact that we can choke to death because our lungs are literally connected to our digestive tract.

  7.  @iveharzing  The no.1 cause of death worldwide is heart disease. At almost twice the rate of the 2nd place killer: cancer. And it kills because of a very simple problem: the brain can't get enough oxygen for a few minutes because blood stopped flowing. A problem that can be circumvented even with a literal hand pump. The heart is almost always the first organ that fails and kills people. And evolution didn't try for redundancy. The kidney has a spare. The lungs has a spare. You can even live with just part of your liver or just part of your brain. But a critically important organ like the heart, we only get one. Neither does it even heal properly. If it's damaged, it builds scar tissue instead of cardiac muscles. Basically messing it all up even more.

  8.  @perwestermark8920  You do realize that modern human life expectancy is more than double that of our ancestors a mere two centuries ago, right?

  10.  @chetansharma6344  Of course it is, as needed to be. Which isn't as profound as you think it is. For most organisms, including us, that just means "live long enough to have kids." Again, the fact that something evolved, rather than having been explicitly designed, doesn't make it more reliable. Evolution has that big flaw of only working with what they already have. Whales had to evolve new ways of storing more blood oxygen, when they could have simply breathed water.

  11. Way to misrepresent the other side. No one thinks human embryos are not life. A clump of cells IS life. The important question is sentience. Human embryos do not develop sentence until at least 4 months, when the brain is developed enough to start working. Prior to that, it really is just a living clump of cells. Unfeeling. Unthinking. Because it's physically not capable of either.

  12. Now imagine this happening at night. When I was around 14, I once made the mistake of doing somersaults underwater in a pool at night. I completely lost sense of up and down and I swallowed water when I started panicking because I really had no idea where up was.

  14. Funny. Tissue is life too. It comes from living trees. But you use it to wipe your butt. And I bet you eat chicken too, without having second thoughts that you're putting "life" in your mouth and chewing. You might as well cry for the eggs being menstruated monthly by women. Or the hundreds of millions of sperm that die every time a man ejaculates (even if one of them succeeds in fertilization). Life is fascinating. But it's not sacred. What makes humans special is the mind. And whether you like it or not, human embryos do not actually have a functioning nervous system until around 4 months.

  15.  @paulmichaelfreedman8334  Per Westermark (the guy I originally replied to) claimed that the cause of the high heart failure rates in modern times is because we don't take care of it with our pampered lifestyle. And now you are saying people lived to 100 in the past because of a pampered luxurious lifestyle. Which is it? And that's what I was saying. The average lifespan of a human being, barring accidents or violent death, is largely dictated by WHEN the heart fails, which averages at 70+, not by any other factor. 1 in 3 people dies of heart failure. Cancer comes second, at 1 in 6 people. No other organ failure due to old age comes close to that level of lethality.

  16.  @7Coolpablo  Yet it's pretty much guaranteed to fail at 70-80, even though the rest of our body can actually survive much longer than that. The heart is the weakest link in our organ systems. Which is ironic considering its function is one of the simplest - it is purely mechanical. Of course, it's absolutely fine for evolution. If all that mattered was having offspring, we should all die by around 45 to 50, the age when women run out of egg cells. But as thinking organisms, we're beyond merely survival by now.

  17. Don't forget the fish part.

  18. The question is not when life begins. It's when sentience begins. It takes around 4 months before the brain and nervous system is developed enough to start transmitting signals (i.e. actually working). It takes 6 months before that brain matures enough to be able to interpret those signals. There's no magic in a fertilized cluster of cells either. Just like there's no magic in the eggs expelled monthly during menstruation in women or the sperm expelled more frequently by men, voluntarily or involuntarily.

  19.  @hungmunk9334  Why the insults? Destin literally talked about this before regarding the political echo chambers on both sides. Listen. We're people, not a 4chan meme. To expand what Flame said: why do you guys somehow have this crazy idea that liberals want to take your guns away? We don't. We want what the NRA once promoted, but don't anymore: gun responsibility. It is not a toy. It is not an accessory to make you look more manly. It is not something you brag about in social media. It is not a fashion item. It is not something you hand over to anyone who asks for it. It is a WEAPON. And weapons need to be treated with respect and caution. I'm sure you don't disagree with that, do you? Also climate change is real. You're literally watching a science channel presented by a rocket engineer.

  25.  @HappyMadScientist  "Nonetheless it sure as heck is more accurate and factual than CNN." HAHAHA One easy way to spot a brainwashed edgelord is someone who thinks one or two specific pundits are the only ones who are telling the truth. The cult of personalities which is why it's so easy for them to harvest your views and your patronage of their books and merch for millions, which in turn encourage them to go even more and more partisan, uncaring of the truth, but becoming an echo chamber. Shapiro and Limbaugh are perfect examples of that.

  26.  @HappyMadScientist  LMFAO What makes you think I'm a Young Turks fan? Get your news and information from a wide range of sources. Learn to gauge reliability on your own by cross-checking sources, knowing who the sources are, and actual facts. You're basically letting talking heads who all have their own agenda and a career built on cultivating YOUR bias do your thinking for you. Did you even watch the video or did you just immediately run to the comments to heap praises on your truthiness idols while spitting curses at your "enemy" faction? It's pathetic how utterly controlled most people are nowadays. You think Shapiro cares about truth? Or Limbaugh? Or the Young Turks? Here's something you should really know about them: how much money they are making. That money they get because they pander to you. If they say something that is inconveniently true but contrary to their audiences' biases, that money goes away. So tell, me. Do you trust them to still tell you the truth? LOL Nope.

  33.  @DangerousOne326  You seem to mistake the development of nerve cells, with having a functioning conscious brain. But then again, you don't exactly seem to understand what "genocide" means either. The lower boundary of what can be defined as "sentience" or "consciousness" is the ability to perceive (and react to) stimuli. This is NOT possible in a fetus until it is around 4 months old for a simple reason: The group of nerve cells that would monitor sensorimotor information is not hooked up to the group of nerve cells that would become the cerebral cortex (the thalamocortical pathway) and vice versa (the corticothalamic pathway). Because neither of them can transmit or receive signals, there is no consciousness. I have sources. Do you? Susan Tawia (1992) When is the Capacity for Sentience Acquired During Human Fetal Development?, Journal of Maternal-Fetal Medicine, 1(3), 153-165, DOI: 10.3109/14767059209161911 Hugo Lagercrantz & Jean-Pierre Changeux (2009) The emergence of human consciousness: from fetal to neonatal life, Pediatric Research, 65(3), 255-260, DOI: 10.1203/PDR.0b013e3181973b0d.

  34.  @DangerousOne326  *facepalm* Of course, you don't know how to read papers.. Nor did you really understand what I actually said. What else did I expect? Someone actually scientifically literate watching a science channel?! /sarcasm You don't become brain dead when you sleep. It's not like sleeping in the same way that a completely disassembled computer (I'm talking about transistors and circuit boards being taken apart) is not on sleep mode. If you had actually read the papers you'd have known that regular cortical EEG activity in fetuses indicative of REM sleep do not arise until 6 to 7 months. Do you even know what synapses are? Or neurotransmitters? Or neurons? Why am I even trying to explain this? You have no interest in actually learning anything about human developmental biology or how brains actually work.

  35.  @DangerousOne326  And yet you still haven't read my sources, nor even give any hint you understand what happens in early brain development. All you've done so far is make a laughable argument that literal unconnected neurons is the same thing as sleeping, and claim you're an expert because you're a doctor. Without actually demonstrating that expertise in the slightest. More telling is how you think a study is automatically unreliable if it's from the 90s. And how you've given me exactly zero sources to back up your arguments. And how you apparently think "MD" and "neurologist" are the same thing. So forgive me if I don't exactly find "trust me, I'm an expert" arguments particularly compelling. If you have nothing else to say but BS like this, I have better things to do elsewhere than argue with a moron.

  36.  @DangerousOne326  You throw statements like this: "A fetus is a human life that is no way ontologically different than a sleeping adult in regards to consciousness." And expect anyone to just accept that at face value. Nothing backing it up, just an emphatic claim that it is supposedly "scientifically accurate". According to what? "The reason I don't have to look at the papers is because I understand the science" No. You really don't. In my entire life I have never met a scientist so full of themselves they think their personal opinion is a better argument than published literature. Stop wasting my time.

  38. Ah, the 90s. When photos were rare semi-precious things. When every time you get photos developed, it's always an event. And you always find that one photo where your finger was on the lens or it got overexposed. And you can't even remember what it was supposed to look like.

  39. *facepalm* why are there so many anti-abortionists who don't seem to understand the difference between life and sentience. People eat caviar and fertilized eggs all the time. YOU probably eat adult chickens all the time. The important thing in the question of abortion is the HUMAN MIND. Whether you like it or not, human embryos DON'T develop a working nervous system until at least 4 months. I'm pro-choice, but I oppose abortions done in the later second or third trimesters precisely for this reason (unless it's life-threatening for the mother). But before that? The embryo is literally incapable of thinking or even feeling anything. If you were arguing about the ethics of killing a potential mind, you might have a point. But acting like early embryos are the same thing as a fully-developed THINKING baby is just stupidity.

  41. Meanwhile in the other side of the ocean, turtles and tortoises have a unique threat in Southeast Asia and Oceania: Chinese traditional medicine. The locals in the Philippines, Malaysia, and Indonesia have been trying to protect turtles for tourism, but Chinese fishing boats (mostly from Hainan) poach them by the thousands per year. And now the situation is even more complicated that Beijing has stolen the SCS.
