Reply to Reflexive fear responses tend to linger in people with anxiety disorders, study suggests by chrisdh79

“However, people with anxiety disorders tend to have a harder time learning to stop being afraid on a physiological level (when the threat is gone) compared to healthy individuals.”

So a certain level of apathy about stimuli that would result in fear is “healthy”? I wonder how high this bar must be right now. Most of us in the U.S. and elsewhere have loved through a pretty traumatic pandemic and rapid-fire violence in our communities.

If our response is “yeah, this is fine” and we don’t have the kinds of anxious responses that the researchers studied that means we’re healthy? Can someone help me out here. As long as I have less emotional response to the violence of my society I’m considered healthy? Is that right? Is my mental health just my capacity to deal with the reality of my experience with minimal interruption?

Build houses out of them and plant more trees in their stead. Rinse and repeat. According to climate scientist Hans Joachim Schellnhuber we have to build 2 billion residential spaces (be it houses or flats) from wood to get CO2 levels down to where they should be

In fact if you treated concrete like a country it would be third on the list of countries that emit the most CO2, right after China and the US. So concrete production produces more CO2 than India with its population of a billion people

AFAIK they even stop burning altogether after a certain point. A charred layer forms that won’t burn. As long as the remaining wood inside this layer is strong enough it won’t fail at all

Reply to comment by [deleted] in Physicists nail down the most precise value yet of the electron magnetic moment. A newly measured value of an electron’s magnetic moment — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. by MistWeaver80

Until it does produces something.

Science goes down so many rabbit holes that even Alice takes a break.

Disproving a theory obviously has its merits as well

Makes sense. In my anecdotal experience, at least.

At age 28 I was diagnosed with Asperger's, so as you can imagine I have a lot of built up anxiety and trauma. I can't recognise novel threats, understand why/how they're threats, or understand how to avoid/solve those threats. Early severe anxiety was rational and life saving, the problem was I had no one to put things into perspective. Usually just either dismissed, shamed me, or punished me. I also have black and white thinking and hyperfocus. It's a huge challenge to overcome lingering fear and overactive startle response, since there often is a legitimate basis for what others assume is irrational.
