> "Our brain chemistry is not stable through our life!"

Citation requested. Because, y'know, it's not like your leg muscles suddenly don't work from age 40-50 and then start working again and we say it's because of unstable "leg chemistry". It's not like your stomach, liver, kidneys, <organs> suddenly stop working after you lose your job or your life partner and we say it's both inexplicable and because of a deficit of "body chemicals" and nod agreement with each other that "body chemistry isn't stable" through a lifetime.

These are just unsatisfyingly crappy non-explanations.

And quick attempts to assume that Doctors, Neuroscientists, Psychiatrists, Psychologists must have a better detailed knowledge of brain chemistry and I'm just falling for nonsense seems to find that they actually don't, and they don't agree that "brain chemistry" is a good explanation, and it can't be measured in a patient, and the idea isn't strongly supported by evidence, and even the mechanism of action of "drugs which correct brain chemistry" isn't agreed on, and when given to people to "correct brain chemistry" it often doesn't make the problem that was blamed on brain chemistry go away.

> "there very well may be genes that control; how much fear someone experiences when riding a roller coaster."

I will lump "genetics" in as another pet-hate unsatisfyingly crappy non-explanation that people tag onto whatever they want so they can stop thinking about it further. There probably are many genes which affect how much fat bodies store, or burn, or food cravings, or what constitutes hunger, or production of various leptins and grehlins and insulins and stomach acids, but that doesn't mean "I'm obese because of my genetics" is any kind of explanation at all. Or "I have this personality because my parents and grandparents had it, it's genetic" is an explanation. Downe's Syndrome is a good use for genetics as an explanation. "I have a macro-scale set of vaguely related behaviours, symptoms and body effects and no clear cause, it's my genetics" isn't.

Even if you have sequenced your genome, and have some specific gene that is associated with extra fat storage, genes can be turned on and off through a lifetime by behaviours and environment. Having a gene from birth doesn't mean it's being expressed and is therefore causing a specific problem, or that the problem can't go away and can't be fixed.

> "The problem society has is telling people that they all should be able to not have feear riding a roller coaster and if you are too afraid to ride a roller coaster you should take xanax."

I agree with this. Society likes assuming everyone is the same. Imagine if we collectively noticed that Adrenaline gives people "a burst of strength" and decided that daily exercise, individual strength training plans, gym visits, were all too much bother and that ageing adults were suffering from "an imbalance of Adrenaline" and when they struggle to carry their massive haul of groceries in from their car they should carry an auto-injector of Adrenaline to help their chemical deficiency.
