The science of why we can’t live forever
Here's why stars fade out — and so do we.
MICHAEL SHERMER: From a scientist's prospective it's going to be rather different from that of most religious traditions, which holds that we die because this is only a temporary staging area before we go to the big show the next stage in which we go to heaven or hell or wherever some kind of afterlife. For scientists the question has a rather different answer and it has to do with the kinds of causes we look for in science. So you have proximate causes versus ultimate causes. For example, why does sugar taste sweet or why does fruit taste sweet something like that? You would say well because there's molecular receptors on your tongue that are geared toward sending signals to a certain part of the brain that register sweetness and pleasure and so on with fruit. That's approximate answer. And ultimate answer is because foods that taste sweet are more likely to be consumed and those in our natural environment are the kinds of foods that are both rare and nutritious and so the more of them you eat the better and we evolved that tendency.
To answer the question why we die, it's the same kind of thing. Approximate answers include cancer, heart disease, arthrosclerosis. The ultimate answer though is found in two principles of nature, that is the second law of thermodynamics or entropy, which means everything runs down, including our bodies. And the whole universe, the whole universe runs down so ultimately even if you could double your lifespan, triple it, live essentially forever you can't really because the universe will eventually die in a heat death. And then second is the principle of natural selection that drives evolution. And it has to do with a cost benefit analysis of how many limited resources you put into organisms. So obviously natural selection is going to select for infants and toddlers and babies to be well cared for, have super regenerative powers to keep their bodies going in order to get the genes into the next generation, get them up to reproductive age and so on. So we see cells that divide very rapidly in infants and babies. A little cut you could practically watch it heal. It's incredible. Whereas someone my age when I get cut it takes much longer to heal.
And so the question is why wouldn't evolution just make it so that I, now in my early 60s, can't just keep going to 200/300? And the answer is there's no reason for it. Because after I've brought my own offspring into reproductive age and then they've brought their offspring into reproductive age I'm really of no use anymore. I can serve a useful purpose as a parent, of course, bringing my genes up and then useful purpose as a grandparent to help my offspring bring their offspring up to reproductive age, but beyond that really there's no sense in pouring any more resources into great, great, great, great, great grandparents because the genes in the little infant are already going to be well taken care of. So it's sort of a weird way to think about it, but in a way nature operates because of entropy. Nature has to select and choose in kind of a triage where are we going to put the resources. I'm saying it like there's somebody up there allocating resources, the government is doling out checks to organisms. No, there is nothing like that, of course, this is just how natural selection operates. So in short, we die so that our future generations may live because there are limited resources.
- According to scientists the reason we die is because the second law of thermodynamics and natural selection.
- The whole universe runs down, so, ultimately, even if you could lengthen your lifespan indefinitely, the universe itself will eventually die in a heat death.
- We die, one predominant view goes, so that our progeny may live — because there are limited resources.

Educators and administrators must build new supports for faculty and student success in a world where the classroom might become virtual in the blink of an eye.
- If you or someone you know is attending school remotely, you are more than likely learning through emergency remote instruction, which is not the same as online learning, write Rich DeMillo and Steve Harmon.
- Education institutions must properly define and understand the difference between a course that is designed from inception to be taught in an online format and a course that has been rapidly converted to be offered to remote students.
- In a future involving more online instruction than any of us ever imagined, it will be crucial to meticulously design factors like learner navigation, interactive recordings, feedback loops, exams and office hours in order to maximize learning potential within the virtual environment.
Can thinking about the past really help us create a better present and future?
- There are two types of counterfactual thinking: upward and downward.
- Both upward and downward counterfactual thinking can be positive impacts on your current outlook - however, upward counterfactual thinking has been linked with depression.
- While counterfactual thinking is a very normal and natural process, experts suggest the best course is to focus on the present and future and allow counterfactual thinking to act as a motivator when possible.

What are upward and downward counterfactual thinking?
Image by one line man on Shutterstock<p><strong>What is upward counterfactual thinking?</strong></p><p>Upward counterfactual thinking happens when we look at a scenario and ask ourselves "what if" in terms of how our life could have turned out better. </p><p>Examples of upward counterfactual thinking are: </p><ul><li><em>"I wish I had taken that other job instead of this one 10 years ago - my life would be so much better if I had." </em></li><li><em>"I wish I would have gotten the part in that high school play, maybe I could have gotten into a theatre school and became an actor…"</em> </li></ul><p>Both of these examples have the ideology that if you had made different choices, your life right now would be improved. </p><p><strong>What is downward counterfactual thinking?</strong></p><p>Downward counterfactual thinking is, naturally, the opposite of upward counterfactual thinking in that we think about how things could have been worse if other decisions had been made. </p><p>Examples of downward counterfactual thinking are: </p><ul><li><em>"I'm so thankful I studied secondary education in university instead of psychology like I had originally planned - I love teaching high school kids and I never would have gotten to do that…" </em></li><li><em>"I'm so happy I left David when I got the chance, I can't imagine still being in an unhappy marriage with someone who doesn't support me…"</em> </li></ul><p>In these examples, we see the idea that if you had made different choices your life would not be as good as it is right now. </p>

How do upward and downward counterfactual thinking impact your life?
Photo by Brasil Creativo on Shutterstock<p>While many people don't see the point in "what if" scenarios, various studies have found that downward counterfactual thinking can be more associated with psychological health compared with upward counterfactual thinking. Not only that, but research has also shown upward counterfactual thinking can be linked with current and future depression.</p> <p><strong>Downward counterfactual thinking tends to be more associated with psychological health </strong></p><p>According to a <a href="http://journal.sjdm.org/jdm06136.pdf" target="_blank">2000 study</a>, downward counterfactual thinking can be linked with better psychological health compared to upward counterfactual thinking. More importantly, in cases where downward counterfactual thinking did lead to negative feelings, those feelings acted as something of a motivator for people to take productive actions to better their current situation. </p> <p><strong>Upward counterfactual thinking tends to be more associated with depression </strong></p><p><a href="https://www.sciencedirect.com/science/article/abs/pii/S0272735816301714#:~:text=An%20upward%20counterfactual%20(as%20opposed,Markman%20and%20McMullen%2C%202003)." target="_blank">According to a 2017 study</a> that pooled a sample of over 13,000 respondents, thoughts about "better outcomes" and regret (upward counterfactual thinking) were associated with current and future depression. </p> <p><strong>Downward counterfactual thinking can actually improve your relationships and is more often engaged in by women than men.</strong></p><p>In a <a href="https://dspace.sunyconnect.suny.edu/bitstream/handle/1951/67589/Studer_Thesis.pdf?sequence=1&isAllowed=y" target="_blank">2016 research paper submitted</a> to the Department of Psychology at the State University of New York at New Paltz, downward counterfactual thinking in regards to romantic relationships was associated with relatively positive relationship outcomes. Interestingly, women were more likely than men to engage in downward counterfactual thinking about their romantic life. </p> <p><strong>Upward counterfactual thinking can have some benefits in certain scenarios. </strong></p><p>When we look back after a failed test and think "I wish I would have studied more" - this motivates us to study harder the next time a test comes up. In this way, upward counterfactual thinking (or the negative version of "what if") can actually benefit us. </p> <p><strong>This can be difficult, though, because much of the time upward counterfactual thinking is more associated with a pessimistic outlook that can be unmotivating. </strong></p> <p>Thinking in the past tense can be motivational (and even healthy) at times, but the best thing to do is look forward. </p><p>While counterfactual thinking as a whole can be used to motivate us to make better choices or appreciate where we are in life, <a href="https://www.psychologytoday.com/us/blog/darwins-subterranean-world/201809/the-psychology-what-if" target="_blank">this Psychology Today</a> article suggests that we should come up with ways to move on and focus on the present and the future instead of the past. Using counterfactual thinking as a motivational tool can be very helpful if we don't get stuck in the "what if" mindset that tends to pull us out of the present and back into the past, where things will always remain the same. </p>

Despite fact check campaigns, anti-vaccination influence is growing.
- Despite announcing plans to combat disinformation, anti-vax groups continue to gain influence on Facebook.
- An analysis of over 1,300 Facebook pages with 100 million followers shows that anti-vaccination agendas are having a profound impact.
- Only 50 percent of Americans are certain they'll receive an approved COVID-19 vaccine.
Facebook announces plan to 'tackle vaccine misinformation'<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="997c512b8b8afcd4db98fdb7ece75680"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/ZTZ3Lq67yiY?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>This trend is having real-world consequences.

While we should be confident of efficacy—gossip about a <a href="https://www.webmd.com/lung/news/20200511/covid-19_vaccine_by_fall_possible_but_at_what_cost" target="_blank">vaccine arriving in the Fall</a> is ambitious and potentially unsafe—the idea that a quarter of the country will refuse any vaccine is a potential public health disaster (as if we're not experiencing one now).</p><p>Making matters worse, we can't fight disinformation with data.

There's no way to tell, but that's the thing about Facebook: it doesn't have to be true. Willis's claim, which he made in conjunction with a fundraising effort for the film, has been shared 4.4k times. Convincing his fanbase that perhaps tens of thousands of doctors aren't on board will be a Herculean task. </p><p>Media Matters notes the official-sounding National Vaccine Information Center (NVIC), which, though sounding governmental, opposes every effort to vaccinate children. Beginning in February, the organization's website started publishing a "<a href="https://www.nvic.org/vaccines-and-diseases/Reports/covid-19.aspx" target="_blank">special report</a>" on COVID-19, laying the groundwork for vaccination disinformation. </p><p style="margin-left: 20px;">"The first three installments of the 'special report' adopt right-wing themes unrelated to vaccines, such as the claim that public health orders that promote social distancing result in a 'loss of civil liberties' and subject Americans to 'quarantine shaming.' The fourth installment, published on March 29, includes the first attacks on vaccine development in the series … The fifth installment of the 'special report,' published on April 1, frames the vaccine development efforts of pharmaceutical companies and other entities as a cash grab."</p>

Why do so many people encounter beings after smoking large doses of DMT?
- DMT is arguably the most powerful psychedelic drug on the planet, capable of producing intense hallucinations.
- Researchers recently surveyed more than 2,000 DMT users about their encounters with 'entities' while tripping, finding that respondents often considered these strange encounters to be positive and meaningful.
- The majority of respondents believed the beings they encountered were not hallucinations.
What are DMT beings?<p>Do DMT entities actually exist in some other dimension, or are they hallucinations that the brain generates when its visual processing system is overwhelmed by a powerful tryptamine?<br></p><p>The late American ethnobotanist Terence McKenna believed that DMT beings — which he called "machine elves" — were real. Here's how he once <a href="https://www.ranker.com/list/dmt-machine-elves-facts/inigo-gonzalez" target="_blank">described</a> one of his DMT experiences:</p><p style="margin-left: 20px;">"I sank to the floor. I [experienced] this hallucination of tumbling forward into these fractal geometric spaces made of light and then I found myself in the equivalent of the Pope's private chapel and there were insect elf machines proffering strange little tablets with strange writing on them, and I was aghast, completely appalled, because [in] a matter of seconds... my entire expectation of the nature of the world was just being shredded in front of me. I've never actually gotten over it.</p><p style="margin-left: 20px;">These self-transforming machine elf creatures were speaking in a colored language which condensed into rotating machines that were like Fabergé eggs but crafted out of luminescent superconducting ceramics and liquid crystal gels. All this stuff was just so weird and so alien and so un-English-able that it was a complete shock — I mean, the literal turning inside out of [my] intellectual universe!"</p><p>McKenna believed machine elves exist in alternate realities, which form a "<a href="https://www.irishtimes.com/culture/books/old-favourites-the-archaic-revival-1991-by-terence-mckenna-1.3924887" target="_blank">raging universe of active intelligence that is transhuman, hyperdimensional, and extremely alien.</a>" But he was far from the first to believe that DMT is a doorway to other realms.</p><p>Indigenous peoples of the Amazon basin have used ayahuasca in religious ceremonies for centuries, though no one is quite sure when they first started experimenting with the psychedelic brew. The Jibaro people of the Ecuadorian rainforest believed ayahuasca allowed regular people, not just shamans, to <a href="https://atrium.lib.uoguelph.ca/xmlui/bitstream/handle/10214/17902/RichardsonG_202004_HonThesis.pdf?sequence=3" target="_blank">speak directly to the gods</a>. The 19th-century Ecuadorian geographer Villavicencio wrote of other Amazonian shamans who used ahaysuca (known as the "vine of the dead") to contact spirits and foresee enemy battle plans.</p><p>In the West, research on DMT experiences has been sparse yet interesting. The psychiatrist Rick Strassman conducted some of the first human DMT trials at the University of New Mexico in the early 1990s. He found that <a href="https://www.erowid.org/chemicals/dmt/dmt_article3.shtml" target="_blank">"at least half"</a> of his research subjects had encountered some form of entity after taking DMT.</p><p style="margin-left: 20px;">"I was neither intellectually nor emotionally prepared for the frequency with which contact with beings occurred in our studies, nor the often utterly bizarre nature of these experiences," Strassman wrote in his book "DMT The Spirit Molecule".</p>
Manuel Medir / Getty<p style="margin-left: 20px;">"Whenever I tried to pull any information out of the entities regarding themselves, the data that was given up was always relevant only to me. The elves could not give me any piece of data I did not already know, nor could their existence be sustained under any kind of prolonged scrutiny."</p><p>It's also worth noting that not all people who smoke DMT see beings, and that some see beings that look <a href="https://www.erowid.org/chemicals/dmt/dmt_article3.shtml" target="_blank">nothing like elves or aliens</a>. The diversity of these reports seems to count against the argument that DMT beings exist in some objective alternate reality.</p><p>In other words, if DMT beings exist in some other dimension, shouldn't they appear the same to anyone who visits that dimension? Or do the beings assume a different appearance based on who's looking? Or are there many types of beings in the DMT universe, but most look like elves? </p><p>You might start seeing elves just trying to sort this stuff out.</p><p>Ultimately, nobody knows exactly why DMT beings take the forms they do, or whether they're just figments of overstimulated imaginations. And the answers might be beside the point. </p><p>In the recent survey, 60 percent of participants said their encounter with DMT beings "produced a desirable alteration in their conception of reality whereas only 1% indicated an undesirable alteration in their conception of reality."</p><p>DMT beings may be nothing more than projections of the subconscious mind. But these bizarre encounters do help some people find real meaning, whether it's through personal revelation or the raw power of ontological shock.</p>
Gender and sexual minority populations are experiencing rising anxiety and depression rates during the pandemic.
- Anxiety and depression rates are spiking in the LGBTQ+ community, and especially in individuals who hadn't struggled with those issues in the past.
- Overall, depression increased by an average PHQ-9 score of 1.21 and anxiety increased by an average GAD-7 score of 3.11.
- The researchers recommended that health care providers check in with LGBTQ+ patients about stress and screen for mood and anxiety disorders—even among those with no prior history of anxiety or depression.
