Ensamhet kan vara farligt. Teorin: känslan ger ett lågintensivt, kroniskt stresspåslag

70 är det nya 50

Delvis är vår kognitiva förmåga, vårt minne, ja till och med vår intelligens, avgjord redan när vi föds. 

Baserat på tvillingstudier har forskare konstaterat att runt hälften av förmågorna är genetiska, andra slår fast att genetiska faktorer står för upp till 80 procent. 

Även risken att utveckla Alzheimers är delvis genetisk.

Pfizer in 2019 sold $20 billion of drugs in the U.S. Its federal tax bill? Zero; Ireland

Trump has already singled out pharma companies and countries like Ireland that reap the benefits of tax-avoidance moves.  Despite its small size, Ireland ran an $87 billion trade surplus with the U.S. last year—larger than any country except China, Mexico and Vietnam. https://www.wsj.com/health/pharma/how-trumps-tariffs-could-upend-pharmas-overseas-tax-strategy-5b8ca758 Is Ireland vulnerable again as the world’s vast shadow banking system starts to crack? Shadow banking is the dog that has not barked during the latest global spasm of financial stress. This is very fortunate, especially for small countries such as Ireland that have bet the farm on this industry. https://englundmacro.blogspot.com/2023/04/is-ireland-vulnerable-again-as-worlds.html Cayman Islands https://en.wikipedia.org/wiki/Cayman_Islands What the heck is happening in the Cayman Islands?

Cognitive blind spots

Bild
Cognitive blind spots are undermining our ability to see the world as it is, rather than as we would like it to be. At the start of the 21st century, western elites generally assumed that globalisation, democracy and the free market were self-evidently good, and would keep spreading, creating peace. N o longer.  FIS, Swiss Federal Intelligence Service, has published a manual about cognitive blind spots. 18 different cognitive biases that hamper our thinking, such as “group think” (adhering to the cosy assumptions of our tribe), “anchoring” (relying exclusively on whatever information we see first, say on social media),  “confirmation bias” (only seeing data that reinforces pre-existing views),  “mirror imaging” (assuming others think like us),  “absence of evidence” bias (failing to think about the data we lack)  and “survivorship bias” (judging data only with success stories, not failures).
