  • Well now you made me go and google it. Some snippets from the top results:

    Evolution. Most female mammals have an estrous cycle, yet only ten primate species, four bat species, the elephant shrew, and one known species of spiny mouse have a menstrual cycle. As these groups are not closely related, it is likely that four distinct evolutionary events have caused menstruation to arise.

    Also:

    To understand why menstruation evolved, we have to think of it as a by-product of spontaneous decidualisation. In most mammals, decidualisation – the thickening of the uterine wall – is controlled by the embryo: it occurs in response to fertilisation rather than in preparation for it. In menstruating species like humans, spontaneous decidualisation is one way the parent tries to wrest back dominance of their uterus from an increasingly invasive embryo. The uterine lining now responds only to the parent’s hormones rather than the embryo’s, and the parent controls whether or not they get pregnant. They put their defences up preemptively, by sealing off the main blood supply from the endometrium before the embryo implants there. Not content with this, the embryo evolved to burrow through the endometrium until it reaches the arteries, where it tears through the wall and rewires the blood vessels so that it can bathe directly in the parent’s blood. The (arguably) ungrateful parasite pumps out hormones to make the arteries expand around it, and paralyses them to prevent the parent from cutting off its supply. It produces more hormones, which act directly on the parent to maintain pregnancy and increase the availability of nutrients. The parent defends themselves as best they can: their endometrium fights against the embryo’s invasive proteins, their immune system attacks the invading cells, and their own hormones try to counteract those of the embryo. The tug-of-war rages on.

    Well that’s just metal af.




  • Have you seen what the cops here do to handcuffed people already on the ground? You’re fucked either way, may as well try to stay in a defensive posture with the ability to (try to) ward off physical attack.

    Also, police confrontations aren’t known for creating calm environments. People make rash and sometimes unreasonable decisions when they are scared or feel threatened.





  • I’m not diagnosed but I “feel you” lol. I never really had a name for it aside from just hitting my limit. There’s no amount of excitement, argumentativeness, sorrow, etc that reaches me after that. It’s like being physically or mentally exhausted but for your emotions. Its never really concerned me though because what am I supposed to do about it?

    Overall it’s a similar response to my social battery. It just wears down to the point where I’ll withdrawal, and if someone tries to push me further I get very snippy and will eventually just leave the area/situation or go completely gray rock until it ends. As I’ve gotten older I’ve noticed I’ve built in escape hatches for myself and have no qualms about just walking out of emotion-ridden situations or even the middle of conversations. You will never see me without control over my own transportation to get home for more than about 30 minutes, and that’s only in emergencies.

    I’ve never really planned my day around it though, as I’ve already built my life around it. I’m reclusive and analytical by nature and any type of strong emotion is usually a bit much for me. I hate sappy movies and songs, I usually refuse to participate in arguments after a certain level of heat is hit, and I find excessive excitement grating to my nerves. My family growing up was always very “extra” to me so they’ve learned they only get a few hours during the holidays before I do the ol’ Midwest knee-slap and hit the road.

    Now the only time I hit my limit is usually during arguments where I am disinclined to leave (like at home with a spouse). Then I just end up looking like a psychopath because I’ll suddenly just kind of shut down and just go numb. My husband says he finds it very unnerving but it’s a pretty rare occurrence.
