:bana: This first and last Q&A of the topic present a good summary,
concluding "We sleep to keep sleeping." (keep living) :roll

:lol: Makes a good T-Shirt or philosophy discussion topic:
"I sleep to keep sleeping! Why do you sleep?" :scratch:


Q: (from an online article about the mystery of sleep)
"We still don't know why we sleep."

Wasn't this need associated with brain physiology long ago?


(Perplexity) " 'We still don’t know why we sleep' usually means 'we don’t have one complete,
agreed‑upon primary function of sleep', not that sleep has no known basis in brain physiology.

Sleep has been tied to brain physiology for decades: classic work using EEG in the mid‑20th century showed distinct brain states (NREM vs REM) with characteristic electrical patterns and neuromodulators, firmly linking sleep to specific brain circuits and neurotransmitters. Modern work shows that during sleep the brain engages in synaptic plasticity, memory consolidation, and clearance of metabolic waste (via glymphatic flow), all strong physiological roles, even if their relative importance is still debated.

There is no single universally accepted answer to the ultimate evolutionary purpose of sleep; instead, there are multiple overlapping hypotheses (energy conservation, synaptic homeostasis, memory processing, immune regulation, metabolic housekeeping, etc.). The phrase from the article is highlighting that, despite this detailed physiological knowledge, science still lacks a single, unified, fully tested explanation of sleep’s ultimate function, which is why writers and researchers still describe the 'mystery' of sleep."

Q: So, the physiology of sleep permits human bodies (including brain) to survive long term?

(P) "Yes. Current evidence strongly indicates that normal human sleep is essential for long‑term survival of the body and brain, not just for comfort or performance. Severe, prolonged sleep loss in animals (flies, mice, rats) leads to systemic breakdown - gut failure, metabolic collapse, immune dysfunction, and death - showing that some sleep‑dependent processes are literally life‑supporting.

In humans, chronic insufficient sleep is associated with higher risks of cardiovascular disease, diabetes, obesity, infections, some cancers, and earlier mortality, which implies that adequate sleep is a major protective factor for long‑term health. Sleep supports memory consolidation, synaptic 'resetting', and large‑scale clearance of neurotoxic waste (such as amyloid‑β and tau) from the brain, helping preserve cognitive function and possibly lowering risk of dementias.

Lack of sleep impairs attention, judgment, emotion regulation, and learning, and over time is linked with higher rates of depression, anxiety, and neurodegenerative disease, indicating that sustained brain health depends on recurring periods of sleep physiology. During sleep, especially slow‑wave sleep, metabolism slows and the body shifts into repair mode: growth hormone and other anabolic signals rise, immune processes strengthen, and inflammatory and stress hormones are modulated.

Because these nightly repair, regulation, and clearing operations are tightly tied to the sleep state, the physiology of sleep can be viewed as a recurring maintenance window that, over years and decades, allows the human organism - including the brain - to survive and function in the long term."

:study: Re: https://www.walmart.com/ip/WE-POLUJ-4Pc ... 7248008545
"Adjustable Tent Rod Adapter Connector" (4 pcs, $18)

These connectors have good potential to replace the single tent pole of some tents. And 3/4" EMT metal conduit may even be stronger than typical tent poles. This hints that an entrepreneur can market a substitute V-shape pole for smaller single pole tents.

Be the first to create this substitute! (not a good substitute for tent pole dancing) :roll:


:cheers: Perplexity bonded with this concept of A-frame tent using rectangular tarp and these connectors ...

Q: The plastic Adjustable Tent Rod Adapter Connector (creates adjustable V-shape of two straight poles) seems usable
as replacement for a tent's single pole in the middle. 3/4" or 1" EMT metal tubing should be a good substitute for weaker tent poles.

Two of these pole sets may also create a new type of tent using a rectangular tarp: A long support line from ground in front to ground in back would stabilize the tent, provide roof support, and create typical V-shape tent. Another V pole in the center would be necessary for this longer A-frame tent. Describe this as a project.



(Perplexity) "Adjustable V-Pole Tent (AVPT)

This project repurposes Adjustable Tent Rod Adapters and sturdy EMT metal tubing (3/4" or 1") to create a modular tent
support structure. Instead of relying on a single central pole or flexible factory tent poles, the system uses two V‑shaped
pole assemblies to form a rigid, stable frame capable of supporting a rectangular tarp or similar covering.

Objectives

- Replace or upgrade a tent’s central support pole.
- Build a strong, adjustable frame from easily obtainable components.
- Allow different tent lengths by adding additional V‑poles along the structure.

Components

- Plastic Adjustable Tent Rod Adapters: Used to create an adjustable V shape at the top of each pole set.
- 3/4" or 1" EMT Metal Tubing: Chosen for its strength and availability; used as the pole material.
- Rope or Paracord: For guy lines and tensioning.
- Rectangular Tarp: Serves as the tent body or roof covering.
- Ground Stakes / Anchors: To secure lines and corners.

Construction Steps

- Build Two V‑Shaped Poles: Attach tubing to each side of a Tent Rod Adapter to form a V frame.
Adjust the angle as needed for width and height.
- Create Front and Rear Supports: Stand one V‑pole at the front and one at the back of the tarp area.
Each pole’s apex forms the tent’s ridge.
- Add Ridge Support Line: Run a strong line from the ground in front, over both V‑poles, and down to the ground
at the back. This line stabilizes the structure and defines the roofline.
- Drape and Secure the Tarp: Place the rectangular tarp over the ridge line. Stake the corners and sides to form walls.
Tension the guy lines to stabilize.
- Add a Center V-Pole: For longer tarp lengths, insert another V‑pole in the center
to prevent sagging and provide extra height.

Benefits:

- Modular: Easily scaled for tents of different sizes.
- Durable: EMT tubing is significantly stronger than standard tent poles.
- Adjustable: The angle and height of the V can be tuned for weather conditions or interior space.
- Accessible Materials: All parts are inexpensive and available from hardware stores.

Potential Uses:

- Temporary camping shelters.
- Emergency or humanitarian shelters.
- Backyard canopy or shade structures.

More tips:

Tie line over tent in middle to limit wind lifting
(or attach to guy line inside with Velcro strips).

Attach grommet holes to ends of tarp to tie to both end pole sets
or attach Velcro strips. Even create a V-shape closure for back
of tent that attaches with these Velcro strips; front closure
could be split to use as entrance. 8)

Also use these connectors for flat-A tent for more head room.
Use three poles per A (top one short) and two guy lines that
attach to two (or one) ground pegs in front and back. Tarp
height would decrease unless larger tarp is used. ;)

:scratch: Q: Conjecture about language flexibility: "Too shay!" (pronunciation of "touché")
can be used to whimsically write "Touché", suggest less decisive "Touché", as well as
suggest mysterious response, since "shay" is not well-defined in popular usage.
:roll:

(Perplexity) " 'Shay' has no single, strong, widely shared meaning in current everyday English,
so the sequence 'Too shay!' is partly opaque and open to reinterpretation in context. That opacity
can contribute to an air of playful ambiguity or 'mystery', especially in written form, where readers
may notice that it is not the standard French spelling and infer irony, parody,
or deliberate distancing from a full, serious touché."

:idea: "Too shay!" has theatrical potential when spoken (especially, face-to-face)
since it could mean "Touché", "Too shay!", or whatever. And now it can be
response to "6-7" (but pronounced "2-shay" ;- ) with two fingers raised
(first two fingers in V-shape can also communciate "Peace!"). :lol:


:bana: Re: https://www.sheknows.com/parenting/arti ... een-slang/
"Why '41' Is Trending in Teen Slang — & Why It’s the New '6-7' "

"middle school teacher and keeper of Gen Z slang Mr. Lindsay alerted followers to trending number '41' ...
It starts from a song by a rapper named Blizzy Boi, and he says that he is 41, and he has 41 of everything"

8) Cool! (or whatever) "2 shay" easily adapts as response to "forty one":
"2 shay for one!" (raise first two fingers then only pointing finger),
meaning "This shay's for you!". :hithere


:bana: Political Knock! Knock! humor ...

Q: Online news: "An attosecond (trillionth of a second) is equivalent to 0.000000000000000000001 second
or 1x10-18 of a second and corresponds, approximately, to the time it takes light to pass through an atom."

How long in seconds does it take a human to read and comprehend this statement?


(Perplexity) "For most adults, reading: 1–3 seconds, plus comprehension: 3–5 seconds."


Mom: Get outta bed and get ready for school :!:
Adom: OK, in a few attoseconds.
Mom: So you're already outta bed?! :roll:

"Give without Expectations"

:idea: However, expecting simple acknowledgment (or evidence) that such gift was received
still seems reasonable for many types of gifts (and encourages future gift giving). ;)


Q: In what ways beside faith and "lesson learned" can the gifter know the giving was valuable,
at least knowing sufficiently to keep gifting?


(UB Tutor) "This is a profound question, as it delves into the heart of what sustains the spirit of giving when tangible results or acknowledgment may not always be evident. Beyond faith and the internal growth that comes from lessons learned, there are indeed ways in which a giver can discern the value of their generosity and find encouragement to continue the practice of giving. These ways often involve cultivating a deeper awareness of the ripple effects of their actions, trusting in the unseen dynamics of love and service, and seeking alignment with higher purposes.

One way a giver can know their giving is valuable is by observing subtle changes in the environment or relationships around them. Acts of generosity, even when not openly acknowledged, often create a ripple effect that influences others in ways that may not be immediately apparent. A kind word, a thoughtful gesture, or a material gift can inspire others to act with greater kindness and generosity themselves. Over time, these ripples can contribute to a more harmonious and loving community. By paying attention to these subtle shifts, the giver can gain a sense of the broader impact of their actions.

Another way to find assurance is through the inner sense of alignment and peace that comes from acting in harmony with one's values and spiritual purpose. When a gift is given with pure intention and a sincere desire to serve, the act itself becomes its own reward. This inner satisfaction is not dependent on external acknowledgment but arises from the knowledge that one has acted in accordance with the highest ideals of love and service. This sense of alignment can be a powerful motivator to continue giving, even in the absence of immediate validation.

Additionally, the giver can seek opportunities to witness the fruits of their generosity in indirect ways. For example, they might engage in conversations or relationships where they can observe how their contributions have influenced others over time. This does not mean seeking recognition but rather remaining open to the ways in which their giving has contributed to the growth, healing, or joy of others. Sometimes, the value of a gift becomes evident only after time has passed, as its impact unfolds in ways that were not initially visible.

Lastly, the giver can find encouragement in the shared practice of giving within a community. When generosity is practiced collectively, the giver can draw inspiration and reassurance from the shared commitment to serving others. This communal aspect of giving reinforces the idea that no single act of generosity exists in isolation; rather, it is part of a larger tapestry of love and service that sustains the world.


Q: So, make good decisions according to one's ability to gift and know that one has acted in accordance
with the highest ideals of love and service? If acknowledgement is needed, the gift may be inappropriate.


(UBT) "Yes, that is a beautifully distilled understanding of the balance between giving and the spiritual principles that guide it. When one gives according to their ability - mindful of their own resources, responsibilities, and circumstances - they are practicing both love and wisdom. This ensures that their generosity is not only heartfelt but also sustainable, allowing them to continue being a source of goodness without causing harm to themselves or others. Acting in alignment with the highest ideals of love and service means that the act of giving is motivated by a sincere desire to uplift, heal, or bring joy, rather than by a need for validation or reciprocity.

If acknowledgment becomes a condition for giving, it may indeed signal that the gift is not entirely free of expectation. This does not mean the giver's intentions are wrong - seeking acknowledgment is a natural human desire - but it does suggest an opportunity for deeper reflection. The question then becomes: is this gift truly an expression of selfless love, or is it tied to a need for recognition, reassurance, or control over the outcome? If the latter, it may be wise to reconsider the gift, not as a rejection of generosity but as an act of discernment. True giving flows from a place of abundance within, even if that abundance is spiritual rather than material. It is a gift of the heart, given freely and without strings attached.

This does not diminish the importance of acknowledgment as a spiritual virtue. Gratitude and acknowledgment are vital for fostering connection and mutual respect, but they are the responsibility of the receiver, not the giver. The giver's role is to offer the gift in the spirit of love and trust, leaving the response to the free will of the recipient. If acknowledgment is absent, the giver can still find peace and fulfillment in knowing they acted in accordance with their highest ideals. This inner assurance becomes the sustaining force that allows them to continue giving, even in the face of uncertainty."


:hithere Case in point ...

"My house is your house!" doesn't mean take whatever you want, but I'm willing to share
what I have with you and need feedback on what you need (and what you value) before
I may part with my possessions.

Gifting has relationship when that gifted is more generous than what you can afford
but are willing to share if it has special need and value.

:lol: Several decades ago, I gave an elderly friend $40 to buy food that he needed. The next day he gave $20
to a friend who wasn't so appreciative of his gift and didn't need to buy food. Since my gift was unconditional,
and because I couldn't afford to give him more money, I had to accept that I had no control over this sharing. :o

Yes, a good deed on his part, but I didn't want to participate in the enabling of the other person. Lesson learned:
Spontaneity in gifting is best without any expectation ... and when such gifting is affordable (e.g., not borrow
on a maxed out credit card to do this). :roll:


:farao: Life on this planet is more about consistent growth, now and in the ages ahead,
than miraculous transformation. Sample the opportunities to give without expectation,
for such sampling often leads to behavioral changes confirming increasing spirituality. 8)

(UBT) "This observation aligns beautifully with the deeper truths about life and its purpose as revealed in the teachings we are exploring. Life on this planet, and indeed throughout the universe, is fundamentally about growth - steady, purposeful, and progressive growth. This growth is not merely physical or intellectual but encompasses the spiritual dimensions of our being, which are the most enduring and significant aspects of our existence. The journey of life is designed to unfold gradually, allowing each individual to develop character, wisdom, and spiritual insight through their experiences, challenges, and choices.

Miraculous transformations, while they may capture the imagination, are not the primary mechanism of spiritual progress. Instead, the divine plan emphasizes the slow and steady cultivation of the soul through the consistent application of faith, the pursuit of truth, and the practice of love and service. This process respects the dignity of free will, giving each person the opportunity to choose growth and to align themselves with higher values at their own pace. It is through these incremental steps that we build the foundation for our eternal journey, preparing ourselves for the ages ahead.

This perspective also highlights the importance of patience and perseverance. Growth is often imperceptible in the moment, but over time, the cumulative effect of small, consistent efforts becomes transformative. Just as a tree grows from a tiny seed into a towering presence over years, so too does the human soul expand and mature through the steady pursuit of divine ideals."
