Grey matter reduces during maturity. Stress (whatever the origin) reduces grey matter. The hippocampus grows a miniscule amount of new grey matter neurons but in general, after the peaking of grey matter growth between the ages of 5-10 years old, it nearly always shrinks. This is not necessarily a bad thing for increased cross-connectivity of neurons reduces the need for so much grey matter. One notable exception is meditation, which increases grey matter volume.

  Why I mention?
I don’t see any significance to BMI and grey matter connection in and of itself, as you can substitute other body stressors such as alcohol, a traumatic event, your boss not saying “thank you”, as reasons equally valid.
=======
Its stress. They’re chasing rabbits down holes, which is fun, but higher hip/waist ratio means internal body fat in the cavity. This compresses organs, stressing their functioning. This additional body stress reduces the amount of blood flow to the brain as it’s being utilized for the stressed organs instead.You can map a similar path for other stressors. I can’t verify — its an intuition – but I’m confident all roads will lead to Rome on this one.

  afaik, aerobic exercises increases grey matter as well as meditation, which is logical, as in both, blood oxygen levels increase and/or vessel relax allowing for slower but better penetration of oxygen into systems.But I suspect “working out” (muscle focus) will show a similar decrease in grey matter volume as you find with high BMI.
=======
For myself, aerobic exercise might as well be poison. I didn’t understand why until I did my genetic stuff through https://codegen.eu/
 
There’s a gene set associated with a phenomenon whereby increased speed of oxygen intake causes a buildup of something related to ATP – probably lactic acid build-up and can be quickly incapacitating.
 
I was THE fastest runner in 3rd, 4th and 5th grade. I gave it 100% and beat everybody BUT at the end, I’d collapse, hoarse breathing, and nurse’s office for 20 mins to recover.
 
Took over 30 years to know why I’d collapse, or why I started feeling physically awful upon hitting that “sweet spot” with aerobic exercise where your body jumps to that “next level” (what they call “fat burning mode”) . I had the “runner’s high” mixed with a feeling like I was dying.
 
And, I sorta was.
 
So, vascillation for increased oxygen via occasional magnesium, keeping various stressors down, (staying centered / an ongoing meditation), etc seems to work.
 
All self-diagnosed but you sort of have to be your own doctor even with doctor availability.

  Loved that meme from my first viewing.I love doing things super fast, maxing out my capabilities. Type at 110 wpm on average with 99+% accuracy, 13.5 notes per second on piano, get me on a real bicycle and I’ll fly.But running? Nothing more than 30s to a minutes. Anything more and everything just shuts down. At least now I know why.

  Love that chart. I’d say I do the same. Probably ADHD, I use my always rambling inner world to organize internal and external stimuli as quickly as possible so that I’m aware of ongoing decision-making reducing errors as much as possible.But I love challenging my System 1. I think 2 feeds into 1 if you allow it.Example: I look at a pile of groceries and can tell you within $5 how much it costs.I don’t know when I started doing that, but I think my subconsious or unconscious number processing just does its thing and by trusting its output, I get to surprise my conscious self with the results.
======
  Another example is my first few replies to your post.I briefly thought, “What does THIS reduction in grey matter have in common with all other reductions in grey matter?”My inner computer pumped out the words: “It’s Stress”.I went to two or three pages to confirm suspicions and I was satisfied that it’s correct enough to say, “It’s factual”.

 Hol’ up dropping a plate would necessarily invoke the amygdala. It’s a fearful moment.
=====
  Even if you consciously laugh it off, that’s just a response to initial fear, with the “laughing it off” as balm.
======
  I never could read all of these faces. I suspect I may have Asperger’s, as “face-blindness” is a symptom, although how can I know what I can’t see :PHowever, WAY BACK around 2002/3, I got an advance copy of METT – Micro Expression Training Tool, https://www.amazon.com/…/ref=cm_cr_arp_d_product_top…I spent some time training with it.It improved my ability to notice flashes of emotion, although certain more complicated emotions, I still could not identify precisely.But at least my speed of recognition went up. I could tell you what it WASN’T, but not necessarily what it was. I still practice when watching people in Youtube videos and on TV on occasion.
=====
  A-HA – this might be more applicable to me. Full PDF is available. Might answer a few questions for me“Differential activation of the amygdala and the ‘social brain’during fearful face-processing in Asperger Syndrome”

Memory is a “read with destructive overwrite”. Excel cells.
=====
 What makes this particularly fascinating to me is that I was diagnosed with “generalized anxiety disorder” as a kid, getting biofeedback lessons, guided meditation, etc.So, ANY activity that was confusing to me could cause anxiety. So, for example, I could interpret a friendly face as menacing or friendly, depending on context. Not just sometimes, but each and every time a uniquely novel experience.I cannot learn that a “smile = friendly / not hostile”. There is no 1:1 correspondence as there might be in a social brain.This is probably why I was always drawn to skepticism for in skepticism, you do not trust what you see and must evaluate each situation fresh utilizing whatever tools you have available to do so at that time.

 I score low-empathy on an empathy quotient test.
Theory of mind issues might finally help explain why “What is the author’s intent?” questions were impossible for me to answer.
_LISTENING COMPREHENSION_I’ll be following these links, especially regarding ToM.

Similarly, people with autism also show deficits in social
behaviour and perform poorly on tasks measuring theory of
mind and empathizing (Baron-Cohen, 1995; Baron-Cohen,
Wheelwright, & Jolliffe, 1997; Baron-Cohen, Wheelwright et
al., 1999; Baron-Cohen et al., 1999a).

  This appears to be when he started going off the rails. Happens with a lot of scientists.But I’ll stick to his early work.
======
 Still, I can’t argue against his high-T hypothesis ’cause it fits me. But I’m going to stay off of that for a bit, focusing on ToM.
=====
  Ok, no. ToM / mindblindness does not apply to me.But I find generalizing a “how would a normal person think or feel?” to be an impossible task.

=====
Logical. I’m at the low end of AQ but I’m in it, just as I’m “just below the “has empathy” line in the EQ test into the “lacks empathy zone”.
 
In short, right on the edge but in a particular side. Interestingly on MBTI, I score INFP _but_ with just the flip or a question or two that I was uncertain of anyway, I can be INTP.
