Sapiens 2

Homo Sapiens is primarily a social animal. Social coorperation is our key for survival and reproduction. It is not enough for individual men and women to know the whereabouts of lions and bisons. It is much more important for them to know who in their band hates whom, who is sleeping with whom, who is honest and who is a cheat.

Over the years, people have woven an incredibly complex network of stories. This accumulates immense social power for humans. The kinds of things that people create through this network of stories are known in academic circles as fictions, social constructs or imagined realities.

An imagined reality is something we all have and that everyone believes in, and as long as this communal beliefs persists, the imagined reality exerts force in the world.

Ever since the cognitive revolution, Sapiens have thus been living in a dual reality. On the one hand, the objective reality of rivers, trees and lions; and on the other hand, the imagined reality of gods, nations and corporations.

Sapiens 1

I am reading a fantastic book called “Sapiens” by Yuval Noah Harari. It is a brief history of humankind.

Here is some of the things from the book I will share with you.

Fire

Gave us power

Farming

Made us hungry for more

Money

Gave us purpose

Science

Made us deadly

We wiped out the Neanderthals.

They were too familiar to ignore, but too different to tolerate.

Sapiens had the unprecedented ability to cooperate flexibly in large numbers. Ants and bees can also work together in huge numbers, but they do so in a very rigid manner and only with close relatives. Wolves and chimpanzees cooperate far more flexible than ants and bees, but they can do so only with small numbers of other individuals that they know intimately. Sapiens can cooperate in extremely flexible ways with countless numbers of strangers.

That´s why the sapiens rule the world, whereas ants eat our leftovers and chimps are locked up in zoos and research laboratories……

Skov bliver ryddet for at skaffe foder til danske svin

Den globale sojaproduktion breder sig og forårsager afskovning og intern fordrivelse af lokale i Sydamerika. Men trods politiske løfter om det modsatte afslører ny rapport en direkte forbindelse til den danske landbrugsindustris import af soja.


Mange grise kræver meget foder. Så når danske landmænd skal mætte de omkring 32 millioner danske svin, så de en dag kan blive til flæskesteg og frikadeller, bruger de proteinrig soja.

Men en ny rapport fra Verdens Skove og den globale miljøorganisation Mighty Earth, som udkommer i dag, viser, at en væsentlig del af den soja, de danske svin spiser, kommer fra områder, hvor store skovområder er ryddet, og hvor lokalbefolkningen udsættes for sundhedsskadelige giftstoffer og fordrives fra deres jord.

»Vi kommer ikke uden om, at dansk landbrug indirekte eller direkte bidrager til den katastrofale udvikling, fordi vi har en enorm svine- og dyreproduktion,« siger Gry Bossen, politisk konsulent i Verdens Skove, som er medforfattere til rapporten.

Træningsmyter

Falder du for disse træningsmyter?

Mytedysten punkterer eller bekræfter tre træningsmyter.

Sved er ikke et tegn på dårlig form

Du behøver for eksempel ikke skamme dig, hvis du er soppet ind i sved, når du skal overgive romaskinen til den næste, for sved er faktisk ikke et tegn på dårlig kondi.

»Faktisk forholder det sig lige omvendt. Veltrænede mennesker sveder som regel mere end utrænede mennesker, og det skyldes, at vores kroppe er gode til at tilpasse sig træningen,« forklarer vært Julie Hermann i videoen.

Når vi træner, har vi brug for at skille os af med varmen og nedkøle kroppen, og det gør vi gennem sved.

Kroppen producerer flere svedkirtler, når vi træner, for på den måde kan vi fortsætte træningen i meget længere tid.

Sundhed på YouTube

Tjek er Videnskab.dk’s YouTube-kanal om sundhed og videnskab.

Formålet med kanalen er at bringe forskningsbaseret viden ud til danske unge.

Kanalen er en del af et større projekt, YouKnowHow, som er støttet af Nordea-fonden.

Chikane af forskere

»Gradueret genoptræning er den mest effektive behandling, vi har, og jeg er virkelig chokeret over, at Cochrane ligger under for pres fra aktivistgrupper,« siger han til Videnskab.dk.

Hovedforfatteren på det tilbagetrukne review, Lillebeth Larun fra Norges Institut for Folkesundhed, siger til Reuters:

»Forsøg på at begrænse, underminere og manipulere evidensbaserede resultater, presse eller intimidere forskere til at opgive deres konklusion, vil i sidste ende få en negativ effekt. Det vil føre til, at man som forsker vælger at arbejde med andre områder, og at der bliver færre ressourcer til at hjælpe de patienter, der har så desperat har brug for det.«

Patienter med kronisk træthedssyndrom er ofte invaliderede af udmattelse. Mange ligger i sengen i årevis.

Folketinget bøjer sig for aktivisterne

Noget tyder på, at aktivisterne, der modarbejder forskerne, ikke kun har haft held med at påvirke Cochrane, men også det danske folketing: For nyligt besluttede et flertal i Folketinget, at kronisk træthedssyndrom skal klassificeres som en neurologisk sygdom i stedet for en funktionel lidelse og have sin egen diagnosekode.

Der er ikke dokumentation for, at kronisk træthedssyndrom er en neurologisk lidelse, og politikernes beslutning går stik imod forskernes og Sundhedsstyrelsens anbefaling.

»Det er yderst problematisk, at politikerne afviser videnskaben og hellere vil tro på det, der kommer fra aktivister. Det er et udtryk for faktafornægtelse,« siger Per Fink.

Når kronisk træthedssyndrom bliver klassificeret som en neurologisk sygdom, og patienterne ikke længere skal henvises til afdelinger for funktionelle lidelser, findes der ingen behandling, som har en dokumenteret effekt.

»Hvis Folketinget forbyder os at anvende de videnskabeligt dokumenterede behandlingsmetoder, der findes, bliver vi selvfølgelig nødt til at opgive at behandle patienterne med kronisk træthedssyndrom,« siger Per Fink.

Hetzen er international

Demonstranterne står ikke længere uden for forskningsklinikken i Aarhus, men deres aktivisme fortsætter på sociale medier, i vrede blogindlæg og i uendelige klager til politikere og myndigheder.

Også i andre lande bliver forskere og læger, der beskæftiger sig med kronisk træthedssyndrom, chikaneret af aktivister, der er vrede over forskningsresultater og uenige i den behandling, forskerne anbefaler.

Det britiske nyhedsbureau Reuters har talt med en halv snes forskere fra Holland, England og Danmark, der er blevet chikaneret.

Mange af dem har valgt at opgive at forske i kronisk træthedssyndrom på grund af den hetz, de udsættes for.

»Alle sagde, at de havde været mål for online-chikane fra aktivister, der protesterer mod deres forskningsresultater. Kun to havde planer om at fortsætte med at forske i behandlinger (mod kronisk træthedssyndrom; red),« skriver Reuters.

Gør hvad du elsker, eller elsk at gøre det du må gøre

Der er ingen tvivl om at det er fedest at leve et liv, hvor du kan gøre alt det du har lyst til at gøre, ikke mindst jobmæssigt.

Der er derfor ingen grund til at forhaste sig, når de unge skal vælge ungdoms- og videregående uddannelse. Det er så utrolig vigtigt, at de får valgt ud fra hvad de virkelig har lyst til at lave nu og her og i fremtiden. Der skal både vælges med hjerte og hjerne. Men ofte er de unge påvirket for meget af hvad andre synes og hvad deres venner gør.

Jeg valgte selv at blive skolelærer fordi jeg gerne vil gøre en forskel for børn og unge. Give dem god inspirerende læring og oplevelser, der giver dem livslyst, glæde, viden og livsduelighed. Det er min mission her i livet. Derudover er lærergerningen også meget varierende fagligt og giver dig faktisk en sund hverdag. Jeg underviser i idræt, biologi og geografi. Disse fag giver mig rigtig god mulighed for bevægelse, frisk luft og spændende oplevelser, hvor mange sanser er i spil.

Denne tur på Odden syd for Køge var forberedelsestid til mit idrætsvalghold. Skønt at kunne tage ud i landskabet og planlægge og blive inspireret til at give børn og unge læring og oplevelser for livet.

Herunder er vi igang med naturcrossfit. 7., 8. og 9. klasses elever på mit idrætsvalghold klar til 700 meter krævende mountainbikerute, derefter 100 meter løb, 3 forskellige styrketræningsøvelser med sten og træstamme på stranden og dernæst passage af å i kano. Af disse forskellige discipliner skal de nå 4 omgange.

Jeg havde selv rimelig travlt med at få padlet kanoen tilbage til de næste hold, så derfor de sparsommelige billeder.

Meant To Be

Today I have a story for you about becoming what you are meant to be. You can say just like H.C. Andersen´s “Den grimme ælling”.

UPWARD & DOWN

The tree in the yard grew vibrantly, upward toward the sky. Its limbs stretched and reached brilliantly, as if to ask:

“Sky, sun, rain, and earth—make me into something great!”

The flowers and the shrubs around the tree watched in awe, waiting, with fresh leaves and strong roots, for this tree to become something great, as they all knew that it would.

The young gardener boy who had planted the tree arrived early one morning, just as winter began to fade and spring began to arrive. He circled the yard, pruned some of the shrubs, picked some of the flowers, and came to a halt at the tree.

The tree had yet to sprout fruit from its branches. But the young boy was patient. He watered the tree, and decided to come back the next season when the tree had developed enough to bear fruit.

Over the summer and into the fall, the whole garden grew, and watched the tree grow, despite itsbarren branches. Through the scorching heat of midsummer evenings, and the shivering cold of the early year, the tree reached up to the sky, as if to plead:

“Sky, sun, rain, and earth—make me into something great!”

The next season, the young boy returned. He circled the yard, pruned the shrubs, picked the flowers, and came to a halt at the tree.

The branches had grown, and hung just over his head, but still, no fruit had emerged from the ends of the limbs. The boy shrugged, pulled out a bag of fertilizer, and spread the rich, heavy soil at the base of the tree. Once the roots were nearly suffocating in nutrients, he stood, brushed the dirt from his hands, and left.

The tree felt stilted as it grew, into the summer and over the fall. It felt outpaced, and unprepared for growing. But the rest of the garden watched it attentively, waiting for fruit to emerge. And yet, it never did. January came quickly, and the tree’s naked branches reached for the white sky, yearning and pleading for something more than itself.

The young boy returned the next season, but instead of circling the garden, he went straight for the tree. He yelled and muttered in disappointment, and kicked the tree’s trunk in anger. The thin, fast–growing bark split open, and the young boy paused, in an instant realization.

He left quickly and returned with shears and clippers. He set up a step stool, and climbed up to prune the branches.

“There,” he said, when the tree had been pruned. “That will teach you to grow fruit. You’re meant to grow fruit. I know this, because I planted you, I did.”

The boy left, and the tree hung, sadly and silently, with sap dripping from its muted branches. But the garden grew forward, into the New Year. The tree slowly recovered, and by the next season, it had renewed itself.

The boy arrived once more, and cursed the tree as he saw the naked branches.

“I planted you, ” he said, with contempt in his voice. “Why won’t you grow fruit, like you should?”

But his anger was short lived. He disappeared and returned quickly, with tape and a knife and a handful of fresh, green branches. The tree watched as the boy sliced into the limbs and grafted on the twigs of another tree. He dumped loads of fertilizer at the base of the tree, stood, and left.

The garden seemed to stretch and warp in the tension of the season, but not compared to the tree itself. The fertilizer accelerated the tree beyond health and beyond movement, and its bark cracked with the explosion of growth. The tree stretched and screamed, but no fruit grew.

The young boy returned to the garden the next season, and his eyes fell in disappointment. The tree stood, torn and stilted, with barren limbs and awkward grafts.

The boy grabbed his axe and called for others to join him. He pointed to the tree, but the other men corrected him, and pointed to the ground around the tree.

He dropped the axe, and retrieved a shovel. He sunk the shovel deep into the earth, to loosen the tree from the ground.

His shovel hit something, hidden in the dirt. He knelt to examine it.

Juice from a bright red fruit spilled into the dirt, split open by the shovel blade. He cleared the dirt to see a vast network of berries, clinging to the roots: Bright, vibrant, and alive.

The freshly awakened smell of the subterranean fruit met his senses.

He stood and threw the shovel aside.

The tree in the yard had grown, vibrantly, upward and down, to become what it was meant to be.

It is all about how you have been formed/raised of your parrent and how you are raising or will raise your children. We have to be formed in a way, but not so much that it kills our passion, interests and competences. We shall not dominate children with our own ambitions.

There are many ways to succed in life.

The most important one
