With all this, I am becoming so much more aware of the changes that neurotransmitters and hormones can make to our view of the world. Things like big changes with hallucinogenic compounds or strong medicines for diseases are obvious, but when you are made aware, especially by a disease the screws them up, you can see the smaller changes in "normal life" as a result.
I think that "normal, normal" people are even more affected than they imagine, but are usually unaware of what is causing the "dsiturbance". Women may be more used to it because of their periodic changes, but men "don't seem to have a reason" to be affected. But our level in testosterone change, adrenaline and noradrenalin levels, and that's even when you are not effected by POIS.
Some luck ones, tend to have delightful neurotransmitter cocktails coursing through their veins all the time, others, just the opposite. We are "seen" as such and such a personality, which we tend to take with more pride or rage (depending) when in reality, we as a personality have a lot less to do with it than we think.
Our personalities are probably a lot more biochemically oriented than we imagine.
So IMAGINE the situation that this generates for a POIS sufferer.
Maybe good to remember when we are beating ourselves up!!
Is there such a field as neuro-philosophy? LOL
