In the vein of laughter being the best medicine.

Cool as he is, Da is gonna lose the fight with that little one.

You’re welcome.
2. On Running…and Natural (read “Functional”) Movement
The MovNat folks (read: Natural Movement) take their cues from French fitness pioneer Georges Hebert, and emphasize a wide variety of functional, natural movements that most modern humans have forgotten. Think Tarzan: climbing, crawling, throwing, heavy lifting, self-defending, swimming, keeping balanced…and walking/running.
Walking and running are still popular forms of exercise, but running is problematic: roughly half the running population each year gets injured in the pursuit of fitness, probably more. Something about how we approach running ends up sidelining way too many of us, and according to MovNat master instructor Danny Clark, it’s actually a comprehensive problem with our modern lack of mobility:
"What I’m going to do today is change your perspective about running. Actually, I have an even loftier goal: I’m going to change your perspective about movement in general. Because once I changed mine, “magical” new doors opened for myself and my students…"
"…let me reiterate a point I’ve made many times now: the root biological purpose of all movement is to be able to complete practical tasks in complex environments…Therefore, it’s logical to deduce that gait patterns-chiefly crawling, walking, and running-have a very real and meaningful purpose for human beings from an evolutionary perspective…all of these gait patterns are essential for our health and well-being."
"The inverse statement is even more potent: In the absence of our ability to practice a variety of basic gait patterns such as crawling, walking, and running, our wellness and overall health will suffer."
3. Stem Cells And Blown Out Knees
"A ‘living bandage’ made from stem cells, which could revolutionise the treatment and prognosis of a common sporting knee injury, has been trialled in humans for the first time by scientists at the Universities of Liverpool and Bristol."
Not an ACE bandage type bandage (perhaps someday). But a membrane seeded with a patient’s own stem cells, which can then differentiate into cartilage cells to replace the damaged meniscal tears common to traumatic knee injuries.
For decades, replacing or regrowing knee cartilage has been the Holy Grail of orthopedic medicine. The vast majority of knee cartilage (meniscal) tears cannot fix themselves: torn menisci stay torn, and after surgical removal of the torn fragment, a weaker filler cartilage grows that is not nearly as robust as the original. Early arthritis and ongoing knee pain and instability can result.
“The procedure involved taking stem cells, harvested from the patient’s own bone marrow, which were then grown for two weeks before being seeded onto a membrane scaffold that helps to deliver the cells into the injured site. The manufactured Cell Bandage was then surgically implanted into the middle of the tear and the cartilage was sewn up around the bandage to keep it in place.
“All five patients had an intact meniscus 12 months post implantation. By 24 months, three of the five patients retained an intact meniscus and had returned to normal knee functionality whilst the other two patients required surgical removal of the damaged meniscus due to a new tear or return of symptoms.
“Professor Anthony Hollander, Chair of Stem Cell Biology at the University of Liverpool and Founder and Chief Scientific Officer of Azellon, said: “The Cell Bandage trial results are very encouraging and offer a potential alternative to surgical removal that will repair the damaged tissue and restore full knee function.”
This article from the New York Times by Lisa Feldman Barrett, a psychology professor at Northwestern University, debunks two of the most commonly held myths about the brain: 1) that we have a triune, or “3-part” brain with “lizard,” emotional, and rational parts, and 2) that sharp seniors have super well-developed cognitive brain centers.
While it’s useful to talk about different aspects of behavior and recommending mental gymnastics as we age to prevent Alzheimer’s, neuroscientists have known for some time that “everything is connected” – functions we call “lizard,” emotional, and rational are shared between different parts of the brain. And the spry and sharp senior brains?
“Our lab used functional magnetic resonance imaging to scan and compare the brains of 17 superagers with those of other people of similar age. We succeeded in identifying a set of brain regions that distinguished the two groups. These regions were thinner for regular agers, a result of age-related atrophy, but in superagers they were indistinguishable from those of young adults, seemingly untouched by the ravages of time.”
“What are these crucial brain regions? If you asked most scientists to guess, they might nominate regions that are thought of as “cognitive” or dedicated to thinking, such as the lateral prefrontal cortex. However, that’s not what we found. Nearly all the action was in “emotional” regions, such as the midcingulate cortex and the anterior insula.
“Brain areas…considered emotional, such as the regions of the “limbic system,” are now known to be major hubs for general communication throughout the brain. They’re important for many functions besides emotion, such as language, stress, regulation of internal organs, and even the coordination of the five senses into a cohesive experience.
“And now, our research demonstrates that these major hub regions play a meaningful role in superaging. The thicker these regions of cortex are, the better a person’s performance on tests of memory and attention…”
And how do you become a superager? Not by crosswords or Sudoku:
“We’re still studying this question, but our best answer at the moment is: work hard at something...these brain regions have another intriguing property: When they increase in activity, you tend to feel pretty bad — tired, stymied, frustrated…the discomfort of exertion means you’re building muscle and discipline. Superagers are like Marines: They excel at pushing past the temporary unpleasantness of intense effort. Studies suggest that the result is a more youthful brain that helps maintain a sharper memory and a greater ability to pay attention.”
