Stamina

From the Roman Empire to the Maya civilization, history is filled with social collapses. Traditionally, historians have studied these downturns qualitatively, by diving into the twists and turns of individual societies.

But a team of scientists has taken a broader approach, looking for enduring patterns of human behavior on a vaster scale of time and space. In a study published in May 2024, the researchers wanted to answer a profound question: Why are some societies more resilient than others?

The study, published in the journal Nature, compared 16 societies scattered across the world, in places like the Yukon and the Australian outback. With powerful statistical models, the researchers analyzed 30,000 years of archaeological records, tracing the impact of wars, famines, and climate change.

The researchers looked for factors that explained why societies in some cases suffered long, deep downturns, while others experienced smaller drops in their populations and bounced back more quickly.

One feature that stood out was the frequency of downturns. You might expect that going through a lot of them would wear societies down, making them more vulnerable to new catastrophes. But the opposite seems to have occurred. They found that going through downturns enabled societies to get through future shocks faster. The more often a society went through them, the more resilient it eventually became.

There's been a lot of research about stress and here's the bad news: it's really bad for your body and your brain. Dr. Rajita Sinha imaged the brains of 100 participants and found that profoundly stressful events (not the normal, day-to-day kinds of stress) can actually shrink the part of your brain called the prefrontal cortex.

In addition, she and her team found that it’s not individual traumatic events that have the most impact, but the cumulative effect of a lifetime’s worth of stress that might cause the most dramatic changes in brain volume.

That area of the brain helps manage our emotions, impulse control, and personal interactions. Smaller brain volumes in these centers have also been linked to depression and other mood disorders such as anxiety.

Dr. Sinha said, “The brain is plastic, and there are ways to bring back and perhaps reverse some of the effects of stress and rescue the brain somewhat.” Relieving stress through exercise or meditation is an important way to diffuse some of the potentially harmful effects it can have on the brain. Maintaining strong social and emotional relationships can also help, to provide perspective on events of experiences that may be too overwhelming to handle on your own.

So, these overstressed individuals may not be able to "just get over it." They may need large amounts of love, patience, and prayer from their church community.

When we think of strength in God’s creation, we might think of elephants but rarely would we think of an octopus. After all, an octopus doesn’t even have any bones, so how could it be very strong? Sy Montgomery writes in The Soul of an Octopus:

Here is an animal with venom like a snake, a beak like a parrot, and ink like an old-fashioned pen. It can weigh as much as a man and stretch as long as a car, yet it can pour its baggy, boneless body through an opening the size of an orange. It can change color and shape. It can taste with its skin.

Yet the octopus is strong, very strong. An octopus’s muscles have both radial and longitudinal fibers, thereby resembling our tongues more than our biceps, but they’re strong enough to turn their arms to rigid rods—or shorten them in length by 50 to 70 percent. An octopus’s arm muscles, by one calculation, can resist a pull one hundred times the octopus’s own weight.

Possible Preaching Angle:

Our creative, powerful God gives gifts of strength throughout his creation even in the most unlikely of places. So how surprising should it be that God gives us strength when we need it to serve him and to resist temptation?

In the dead of night at the heart of the Colombian jungle, army radios crackled to life with the message the nation had been praying for: "Miracle, miracle, miracle, miracle." The military code revealed that four children missing in the jungle for 40 days had all been found--alive.

The youngsters, all members of the indigenous Huitoto people, had been missing since the light plane they were travelling in crashed into the Amazon on May 1, 2023. The tragedy killed their mother and the two pilots and left the children--aged 13, nine, four, and one--stranded alone in an area teeming with snakes, jaguars, and mosquitos.

Rescuers initially feared the worst, but footprints, partially eaten wild fruit and other clues soon gave them hope that the children might be alive after they left the crash site looking for help. Over the next six weeks, the children battled the elements in what Colombia's President Gustavo Petro called "an example of total survival which will remain in history."

If there were ever children well-prepared to tackle such an ordeal, the Mucutuy family were the ones. Huitoto people learn hunting, fishing, and gathering from an early age, and their grandfather told reporters that the eldest children were well acquainted with the jungle.

Speaking to Colombian media, the children's aunt said the family would regularly play a “survival game” together growing up. She recalled, “When we played, we set up little camps. Thirteen-year-old Lesly knew what fruits she can't eat, because there are many poisonous fruits in the forest. And she knew how to take care of a baby.”

After the crash, Lesly built makeshift shelters from branches held together with her hair ties. She also recovered fariña, a type of cassava flour, from the wreckage of the Cessna plane they had been travelling in. The children survived on the flour until it ran out and then they ate seeds. The fruit from the avichure tree, also known as milk tree, is rich in sugar and its seeds can be chewed like chewing gum.

But they still faced significant challenges surviving in the inhospitable environment. Indigenous expert Alex Rufino said the children were in “a very dark, very dense jungle, where the largest trees in the region are.” In addition to avoiding predators, the children also endured intense rainstorms.

John Moreno, leader of the Guanano group in the south-eastern part of Colombia where the children were brought up, said they had been "raised by their grandmother," a widely respected indigenous elder. He said, “They used what they learned in the community, relied on their ancestral knowledge in order to survive.”

Possible Preaching Angle:

It is the duty of parents and the church community to train up children to survive and thrive in the hostile environment of the world. It is literally “a jungle out there” for our children and they must be prepared when they are young.

Muscular dystrophy, spinal injury, and other medical issues can cause progressive weakness and loss of muscle mass in a patient’s arms. Over time, muscle weakness decreases mobility, making everyday tasks difficult. But, a pioneering set of “wearable muscles” with a profile like a shoulder sling, could increase mobility and strength in the arms of people who have lost it. As algorithmic intelligence advances, engineers are attempting to design prosthetics to replace lost mobility, but many are large, bulky, or extremely expensive.

Michael Hagmann has a rare form of muscular dystrophy called Bethlem myopathy, but his muscular output was increased 61% thanks to a kind of exo-tendon called “Myoshirt.” Smart algorithms detect the user’s movements and the assistance remains always in tune with them. The mechanical movements can be tailored to their individual preferences, and the user is always in control and can override the device at any time.

The Myoshirt is a soft, wearable exo-muscle for the arms and shoulders. It is a kind of vest with cuffs for the upper arms accompanied by a small box containing all the computer technology. At the moment, the box containing the motor and computer parts weighs close to 9 pounds. So, the team’s first priority is to develop a full prototype with an even more discreet profile to allow people to use it in day-to-day life.

Possible Preaching Angle:

In the spiritual realm, believers have a disabling weakness due to the “disease” of sin and often do not have the strength they need to do the will of God. However, God’s strength can provide all the spiritual power we need to obey and serve him. “He gives strength to the weary and increases the power of the weak … but those who hope in the Lord will renew their strength …” (Isa. 40:29-31).

The last thing a police officer trying to chase down a suspect in a high-speed pursuit needs to see is a warning that their patrol car is running low on gas—or on battery juice. But that’s how it went down one night in Fremont, California. The police officer pursuing a suspect while driving the department’s Tesla Model S patrol car noticed it was running out of battery power.

The pursuit of a “felony vehicle” started in Fremont and reached peak speeds of about 120 miles per hour on the highway. The officer driving the Tesla radioed in to dispatch that he might not be able to continue the chase he was leading. Officer Jesse Hartman said, “I am down to six miles of battery on the Tesla so I may lose it here in a sec.”

However, shortly after Hartman called, the person the police were chasing began driving on the shoulder of the highway as traffic was thickening. This prompted police to call off the chase at that moment for safety. The vehicle being chased was found a short time later after it crashed into bushes, but the driver had fled the scene and was not found. Officer Hartman eventually found a charger in San Jose to juice up his car.

A police department spokesperson said, “We have no written policy regarding charging, but the general guideline is that it should at least be half full at the beginning of the shift.” Apparently, the Tesla had not been recharged after the previous shift before Hartman took it out, so the battery level was lower than it should have been. A spokesperson couldn’t provide details on why it wasn’t charged.

Endurance; Holy Spirit; Power; Spiritual Warfare: Christians may also be running on empty unless they connect daily to the power of the Spirit. Only then will they have endurance in the struggle against temptation and the ability to do God’s will.

In 1975, Salvatore Maddi, a psychologist at the University of Chicago, began to study the long-term impact of stress on employees at the Illinois Bell Telephone Company. It was supposed to be a simple longitudinal study. But in 1981, Congress passed the Telecommunications Competition and Deregulation Act, and the entire industry was disrupted. Within one year, Bell Telephone laid off half its workforce. Those who were left faced uncertainty, changing roles, and increased demands. As Maddi recalls, "One manager told me he had ten different supervisors in one year, and neither he nor they knew what they were supposed to do."

Some employees crashed and burned under the pressure, developing health problems and depression. Other employees thrived, finding a new sense of purpose and enhanced well-being. Because Maddi had been studying these employees for years, he began to search for clues in how they had responded to the stress.

A few things stood out about people who thrived under stress. First, they thought about stress differently. They saw it as a normal aspect of life, and they didn't believe that it was possible or even desirable to have an entirely comfortable, safe life. Instead, they viewed stress as an opportunity to grow. They also believed that difficult times required not isolating oneself. Finally, no matter what the circumstances, these "thrivers" believed we must continue making choices—ones that could change the situation or, if that wasn't possible, that could change how the situation affected them. People who held these attitudes were more likely to take action and to connect with others during stress.

Maddi named this collection of attitudes and coping strategies "hardiness," which he defined as the courage to grow from stress. Since that study of Bell Telephone employees, the benefits of hardiness have been documented across countless circumstances, including military deployment, immigration, living in poverty, battling cancer, and raising a child with autism, as well as in professions ranging from law enforcement and medicine to technology, education, and sports.
