Mind hack: How to push past fear
Fear, not empathy, is the most powerful emotion in the world.
Karen Palmer is the Storyteller from the Future. She is an award-winning international artist and TED speaker. She creates immersive film experiences at the intersection of film, A.I. technology, gaming, immersive storytelling, neuroscience, consciousness, implicit bias, and the parkour philosophy of moving through fear. She is the creator of RIOT, an emotionally responsive film, which uses facial recognition and A.I. technology to navigate through a dangerous riot.
KAREN PALMER: I am not so much of a pro-empathy chick. I feel, this is just my personal opinion that I don't feel empathy is the one and that it has been the one for the past few years and I don't think things are getting any better. In fact, things are getting worse, right. I feel a lot of this oh, I understand how you feel. That's not helping me so to me personally it's a very passive emotion. And my number one priority is moving through fear because I feel that fear is the most powerful emotion that is in the world and that most of my emotions, other people's emotions I believe is governed or influenced by fear. Like oh, I can't leave my job. I hate my job, I can't leave my job. How will I live. I can't leave this guy or I've got to hang out with this chick, I need them. If we can kind of move through our fear and also I feel that how we're being influenced and manipulated by the media is very strategically playing on people's fears.
So if we can kind of as opposed to focus on oh you, how are you feeling and focus on ourselves and take responsibility for our actions and move through that. That is the number one focus of my work. Enabling you to move through your own personal fear.
So I'm very much inspired by parkour and I am still am a freerunner but I was a really hardcore freerunner training like six, seven days a week for two years at one point like a decade ago, 12 years ago in my life. And I basically didn't realize at the time but me and the people that I trained with were basically completely rewiring our brain. We were learning to understand and our own, we were learning to understand our own personal triggers for fear and then navigate through there. So say that we were jumping on a ledge that if we fell we might break both our legs. And the distance was quite manageable so what we'd do is we'd start on the ground. Then we'd go up a little bit higher, go up a little big higher. The same distance but as you go higher it's not the distance, it's the consequences that scare you.
So we learned to master our own fear and develop strategies for moving through fear. And often in life when we feel fear we kind of get nervous and we run from it. But really when you feel fear it's something new and probably that's a direction not all the time but often that we should be moving toward to embrace something new. I felt so empowered that it inspired me to change my life like leave my boyfriend, leave my job, change my flatmate, change my business partner, everything. Because I was like well if I can train and I'll jump on this wall and I didn't break my legs what's the worst that can happen if I split out with my boyfriend and I don't think he's the one, right. I basically reprogrammed my brain. And then from that I was able to change my whole life and be sitting here with you today, right.
So with my work I was inspired over many years. Again, it's about a decade to try and break that down and distill that into a process that can be translated into a user experience within immersive storytelling and digital art. And that's basically film and behavioral psychology where the film, you see a narrative. You're kind of governed and motivated by your fear and that you get a response. And if you're happy with the response you could then go back into the experience and change your narrative. Focus on your breathing, relax, think about your motivation, whatever that thing is so that you could basically move through your fear. And then once you've done it once the kind of key is with parkour is that we kind of say well, you've got to do something three times. And that is kind of like quite a common thing when you're trying to master something. Once is like, you can do it twice and three times now you've mastered it. And that's because neurologically it kind of takes you three times for your neurons to fire in your brain and to create those new pathways. Then it's like sealed. So my film enables this process through a storytelling experience which is cool and fun and exciting and dynamic. It doesn't feel like work. It doesn't feel like you're doing some meditation app or anything. It just feels really cool. So it's got a combination of parkour philosophy, science, filmmaking and storytelling.
- Karen Palmer's work as a storyteller is about helping others focus on themselves and take responsibilities for their actions.
- Freerunning and parkour taught Palmer the power of pushing past fear to reach and exceed one's goals. By learning to understand personal triggers for fear, humans can effectively rewire their brains.
- Fear is a reaction to something new, which is often the direction we should be moving towards and not away from.

New research establishes an unexpected connection.
- A study provides further confirmation that a prolonged lack of sleep can result in early mortality.
- Surprisingly, the direct cause seems to be a buildup of Reactive Oxygen Species in the gut produced by sleeplessness.
- When the buildup is neutralized, a normal lifespan is restored.
We don't have to tell you what it feels like when you don't get enough sleep. A night or two of that can be miserable; long-term sleeplessness is out-and-out debilitating. Though we know from personal experience that we need sleep — our cognitive, metabolic, cardiovascular, and immune functioning depend on it — a lack of it does more than just make you feel like you want to die. It can actually kill you, according to study of rats published in 1989. But why?
A new study answers that question, and in an unexpected way. It appears that the sleeplessness/death connection has nothing to do with the brain or nervous system as many have assumed — it happens in your gut. Equally amazing, the study's authors were able to reverse the ill effects with antioxidants.
The study, from researchers at Harvard Medical School (HMS), is published in the journal Cell.
An unexpected culprit
The new research examines the mechanisms at play in sleep-deprived fruit flies and in mice — long-term sleep-deprivation experiments with humans are considered ethically iffy.
What the scientists found is that death from sleep deprivation is always preceded by a buildup of Reactive Oxygen Species (ROS) in the gut. These are not, as their name implies, living organisms. ROS are reactive molecules that are part of the immune system's response to invading microbes, and recent research suggests they're paradoxically key players in normal cell signal transduction and cell cycling as well. However, having an excess of ROS leads to oxidative stress, which is linked to "macromolecular damage and is implicated in various disease states such as atherosclerosis, diabetes, cancer, neurodegeneration, and aging." To prevent this, cellular defenses typically maintain a balance between ROS production and removal.
"We took an unbiased approach and searched throughout the body for indicators of damage from sleep deprivation," says senior study author Dragana Rogulja, admitting, "We were surprised to find it was the gut that plays a key role in causing death." The accumulation occurred in both sleep-deprived fruit flies and mice.
"Even more surprising," Rogulja recalls, "we found that premature death could be prevented. Each morning, we would all gather around to look at the flies, with disbelief to be honest. What we saw is that every time we could neutralize ROS in the gut, we could rescue the flies." Fruit flies given any of 11 antioxidant compounds — including melatonin, lipoic acid and NAD — that neutralize ROS buildups remained active and lived a normal length of time in spite of sleep deprivation. (The researchers note that these antioxidants did not extend the lifespans of non-sleep deprived control subjects.)

The study's tests were managed by co-first authors Alexandra Vaccaro and Yosef Kaplan Dor, both research fellows at HMS.
You may wonder how you compel a fruit fly to sleep, or for that matter, how you keep one awake. The researchers ascertained that fruit flies doze off in response to being shaken, and thus were the control subjects induced to snooze in their individual, warmed tubes. Each subject occupied its own 29 °C (84F) tube.
For their sleepless cohort, fruit flies were genetically manipulated to express a heat-sensitive protein in specific neurons. These neurons are known to suppress sleep, and did so — the fruit flies' activity levels, or lack thereof, were tracked using infrared beams.
Starting at Day 10 of sleep deprivation, fruit flies began dying, with all of them dead by Day 20. Control flies lived up to 40 days.
The scientists sought out markers that would indicate cell damage in their sleepless subjects. They saw no difference in brain tissue and elsewhere between the well-rested and sleep-deprived fruit flies, with the exception of one fruit fly.
However, in the guts of sleep-deprived fruit flies was a massive accumulation of ROS, which peaked around Day 10. Says Vaccaro, "We found that sleep-deprived flies were dying at the same pace, every time, and when we looked at markers of cell damage and death, the one tissue that really stood out was the gut." She adds, "I remember when we did the first experiment, you could immediately tell under the microscope that there was a striking difference. That almost never happens in lab research."
The experiments were repeated with mice who were gently kept awake for five days. Again, ROS built up over time in their small and large intestines but nowhere else.
As noted above, the administering of antioxidants alleviated the effect of the ROS buildup. In addition, flies that were modified to overproduce gut antioxidant enzymes were found to be immune to the damaging effects of sleep deprivation.
The research leaves some important questions unanswered. Says Kaplan Dor, "We still don't know why sleep loss causes ROS accumulation in the gut, and why this is lethal." He hypothesizes, "Sleep deprivation could directly affect the gut, but the trigger may also originate in the brain. Similarly, death could be due to damage in the gut or because high levels of ROS have systemic effects, or some combination of these."
The HMS researchers are now investigating the chemical pathways by which sleep-deprivation triggers the ROS buildup, and the means by which the ROS wreak cell havoc.
"We need to understand the biology of how sleep deprivation damages the body so that we can find ways to prevent this harm," says Rogulja.
Referring to the value of this study to humans, she notes,"So many of us are chronically sleep deprived. Even if we know staying up late every night is bad, we still do it. We believe we've identified a central issue that, when eliminated, allows for survival without sleep, at least in fruit flies."
We must rethink the "chemical imbalance" theory of mental health.
- A new review found that withdrawal symptoms from antidepressants and antipsychotics can last for over a year.
- Side effects from SSRIs, SNRIs, and antipsychotics last longer than benzodiazepines like Valium or Prozac.
- The global antidepressant market is expected to reach $28.6 billion this year.
Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?
Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.
Or is doubt a self-fulfilling prophecy?
