What did you learn today?

I learned that there is a spider species that has mating behavior like a bird of paradise. Peacock spider. Even has a brightly colored patterned abdomen that it flips up like peacock feathers (hence its name). This little guy is so small you wouldn't really ever even notice them doing their thing in your backyard. Like 2mm. Arachnidae are so cool...

I learned that the shellfish allergy that I've developed over the last few years and so far only ever made me itchy, now causes catastrophic diarrhea.

And a good time was had by all.
My wife can't eat shellfish so I rarely eat it. A friend of mine developed an allergy to shrimp when he was in his fifties. His doctor warned him that he would probably die if he ate it again. Be careful.

I can really appreciate what both of you are going through. I was 18 years old when I ate Lobster for the first time. I had no idea it was an allergy the first time, but the 2 subsequent attempts at Lobster after the first confirmed to me it was an allergic reaction. Swollen, itchy gums, my throat closing up, runny nose, puffy eyes, the same symptoms I have when I am around cats. Oddly enough, I also had itchy and swollen gums after eating fried Calamari. I stay away from all seafood now since I don't carry a Epi pen with me. I could only imagine how much the copay on one of those is now.

Whatever this is started four or five years ago when some soft shell crab made my whole body red and itchy like never before. I stayed away from shellfish for a while and when I tried it again it just got me mildly itchy. I never had any kind of swelling or breathing problems but the last few times I ate any shellfish, it destroyed my stomach. I'm afraid what it'll do next if I try again. I don't seem to have any problem with fish, which is good.

How does your stomach react to Klingon Gagh, any similar symptoms?

"Oxytocin, the first element in the neurobiology of bonding, is an important driver of both care and prejudice."
Why ‘care’ and the ‘scare’ are inseparable when you love someone.
A large molecule produced mainly by neurons in a small region of the brain called the hypothalamus, oxytocin is known for coordinating bonding, sociality, and group living. From the hypothalamus, oxytocin targets receptors in the body and the brain, primarily the amygdala, a centre for fear and vigilance; the hippocampus, where memory resides; and the striatum, a locus of motivation and reward. Through these pathways, the bonding hormone, oxytocin, functions with the precision of a neurotransmitter and the longevity of a hormone, reaching faraway locations and broadly influencing behaviour. Importantly, oxytocin is released not only through the central part of the neuron, but also its extensions, called dendrites. The dendrites are primed to increase oxytocin release whenever attachment memories are invoked. This way, early attachments prime us for a lifetime, and we keep seeking echoes of early experiences in later relationships, whether being carried on mother’s back throughout the day or exploring nature with father.

Memory of these early attachments helps us re-enact the unique state that Sue Carter, a neurobiologist at the University of Indiana, calls ‘immobility without fear’. These same memories enable what the English psychoanalyst Donald Winnicott in 1958 described as ‘the capacity to be alone’ in the presence of someone in a state of peace, serenity and transcendence, where aloneness is not loneliness.

Coronavirus appears to use the ACE-2 receptor as a point of entry.
Novel coronavirus receptors show similarities to SARS-CoV, according to new analysis
There are actually some blood pressure meds(ACE inhibitors) but the most common do not use ACE-2, they use ACE(1) i.e. Lisinopril.
Using ACE-2 type may lower risk of getting the virus due to ACE-2 "parking spots"/receptors being used:
What to know about angiotensin II receptor blockers
Just be careful of the ACE-2 side effect of hyperkalemia(retention of potassium that can be very bad with heart rates), possibly eat potassium-reducing foods nad/or foods without potassium.

The genetic odds indicate this is a biased virus as it is more easily obtained by Japanese and Asians, "white folks” being the least likely to get it per ACE-2 body composition.

View attachment 3719852

If one DOES get it, taking mild forms of blood pressure meds that work on the ACE-2 receptor may help as will cardiac meds that slow heart rate somewhat as one of the secondary forms of damage is myocarditis(inflammation of the outer heart muscle) leading to heart failure(https://www.acc.org//~/media/Non-Cl.../S20028-ACC-Clinical-Bulletin-Coronavirus.pdf).
Destressing the heart muscle would be useful if one is fighting this virus.

Thanks for the update.:thumbsup:
