A Tale Of Nine Lives by Akimiya Jun

The whole "the brain isn't fully mature until age 25" bit is actually a fairly impressive bit of psuedoscience for how incredibly stupid the way it misinterprets the data it's based on is.

Okay, so: there's a part of the human brain called the "prefrontal cortex" which is, among other things, responsible for executive function and impulse control. Like most parts of the brain, it undergoes active "rewiring" over time (i.e., pruning unused neural connections and establishing new ones), and in the case of the prefrontal cortex in particular, this rewiring sharply accelerates during puberty.

Because the pace of rewiring in the prefrontal cortex is linked to specific developmental milestones, it was hypothesised that it would slow down and eventually stop in adulthood. However, the process can't directly be observed; the only way to tell how much neural rewiring is taking place in a particular part of the brain is to compare multiple brain scans of the same individual performed over a period of time.

Thus, something called a "longitudinal study" was commissioned: the same individuals would undergo regular brain scans over a period of mayn years, beginning in early childhood, so that their prefrontal development could accurately be tracked.

The longitudinal study was originally planned to follow its subjects up to age 21. However, when the predicted cessation of prefrontal rewiring was not observed by age 21, additional funding was obtained, and the study period was extended to age 25. The predicted cessation of prefrontal development wasn't observed by age 25, either, at which point the study was terminated.

When the mainstream press got hold of these results, the conclusion that prefrontal rewiring continues at least until age 25 was reported as prefrontal development finishing at age 25. Critically, this is the exact opposite of what the study actually concluded. The study was unable to identify a stopping point for prefrontal development because no such stopping point was observed for any subject during the study period. The only significance of the age 25 is that no subjects were tracked beyond this age because the study ran out of funding!

It gets me when people try to argue against the neuroscience-proves-everybody-under-25-is-a-child talking point by claiming that it's merely an average, or that prefrontal development doesn't tell the whole story. Like, no, it's not an average – it's just bullshit. There's no evidence that the cited phenomenon exists at all. If there is an age where prefrontal rewiring levels off and stops (and it's not clear that there is), we don't know what age that is; we merely know that it must be older than 25.

What if senshi found izutsumi sooner

I don’t even fucking like tomatoes. When was the last time you ever saw me eating a tomato? It’s a fucking vegetable. Or a fruit. Why would I want to eat something that can’t even make up it’s mind

my stupid son

Reblog if, no matter the size of the role, you would agree to work with the Muppets if offered the chance to do so, no questions asked

I hope you know that your stuff genuinely brightens my day papa senshi and baby izutsumi is literally getting me thru it,,,, love your stuff,,, <3

I'm happy those sillies make you happy :)

I saw a post a little while ago that I'll never find again, but it's still bugging me. It was written like a PSA about proper procedure for applying testosterone gel--mainly, how you're not supposed to let it get on anyone else's skin.

And that's correct. But the post went hard on it, like "please, please be aware of the risks of this medication, it can do so much damage to others if you're not careful, I just think we should be honest about the advantages and disadvantages of medications like this."

It could've been sincere, but it gave me concern-trolling vibes real bad and I can't get it out of my head. So here's my PSA:

Don't slap on your T-gel and then immediately rub your bare bicep on anyone.

Once 2 hours have passed, the remaining amount available to be absorbed is negligible. The med guide says to wash your bicep before you rub it on anyone, but even that's being extremely cautious.

Testosterone isn't poison. If you apply a full dose every day, it still takes months before anything noticeable happens. It's not going to kill someone who accidentally touches your skin for .5 milliseconds.

You do not have to handle T-gel like it's drain cleaner. It's not corrosive. Cis women have testosterone. It's a thing that humans have in our bodies. Avoid getting your medication onto anyone else, but holy shit nothing bad is gonna happen if you forget one time and snuggle shirtless.

T-gel is alcohol-based, so it's best to refrain from being on fire until it has dried thoroughly.

Don't put it on your dick. If you've ever accidentally or on purpose gotten IcyHot on your dick, you have an intuitive understanding of how the skin there differs from bicep skin. Also, the effects of testosterone gel don't localize like that and your dick is fine, I promise.

Don't eat it. I don't know why you'd want to, but don't.

Don't leave the bottle out around little kids on account of little kids being the way that they are, i.e., enthusiastic about potions.

It's "See how well you can follow instructions" time ya lil fuckers!!

You all have one week, let's see how this goes

@maryland-no-rabies Tagging cause I need people to see this

Have fun !!

I think there's a widespread school of thought that old or nearly immortal beings like elves and draculas and shit have developed some kind of centuries long ageless patience. An attitude something like, "I have seen empires rise and fall, rulers come and go. This too will pass in the blink of an eye, and matters not to the world."

But I also like ancients who are like do what you want forever. "Are you kidding, a century ago everyone was wearing skirts. Wear pink, sleep in a tree, dance in the street, climb up the walls, talk to strangers. No one's gonna give a shit in a hundred years, have fun now!"
