In-lightened

Ever since I can remember, I've experienced this phenomenon that just seems to happen out of the blue.

My eyes are closed -at any time of the day- and suddenly I start to see yellow or white lights. Either a donut shape that starts out big and becomes smaller and smaller, until it fades away or dots all over, more often than not, in motion. Sometimes if I rub my eyes I can get these visions up and running too. I have also experienced more than once that after looking at something in the sunlight and then closing my eyes, I see shapes in lights and shadows of what I was just looking at. Like and after-image.

What the phosphene?

Apparently, this light is coming from inside our eyes. In the same way that fireflies and deep-sea creatures can glow, cells within your eyes emit biophotons, or biologically produced light particles.
Phosphenes are like visual noise our retinas make, they can also be activated by stimulating our retinas with pressure. Even without pressure it is a completely normal biological function, determined by the way our eyes and brain communicate with each other, agreeing on what kind of light it is we are seeing, outer or inner.

Please read these articles to understand a little bit more in depth, otherwise sit back and enjoy the show. I know I do.

The fifth taste

One of my all-time favorite things in the world is undeniably food. It is among my top 3 reasons to travel, and in my daily life, I generally put a lot of thought into it.

I lived in Indonesia for a year in 2015-16 and like I stated on my previous post, I've recently returned. One of my favorite things about Indo is its food. Yet it is only a few days ago that I found out about MSG and ultimately made the connection to already knowing about this decades ago from home and the famous use of Ajinomoto in Ecuadorian cooking.

But what on Earth is Monosodium Glutamate (MSG)?

Long story short, it is a very commonly used flavor enhancer. It is known to trigger the fifth taste known as umami* or savory taste. FYI, the other basic tastes are sweet, sour, bitter and salty. It tricks your brain (via your tastebuds) into believing it is consuming something tastier and actually nutritious. Unfortunately, it is not only added to industrial ready-made foods, such as chips, frozen goods or broths, but also to households and local cuisine everywhere and I mean everywhere in the world; Japan, USA, Ecuador, Indonesia, to name just a few. 

Simple made complicated, it is an excitotoxin, which like the name suggests, overexcites the cells to potentially harmful levels that can in the long run cause serious cell damage and we all know what that can lead to.

Funny thing is, the idea for MSG came from a natural seaweed broth that once upon a time blew the tastebuds out of someone.

Before ever moving here I thought it'd be though to stick to a healthy vegetarian diet, but when I arrived I was pleasantly surprised that it was pretty simple given the fine array of veggie options in the local warungs or food stalls around. I, blissful in my ignorance, enjoyed this last year to the fullest, now that I have this information, I can't yet let it go. What I've done is I found a local warung that I love and just asked if they use it, they said no. Is it true or not? I guess I will never know and I can honestly say that I will keep going back either way 😔

*Discovered by MSG (Ajinomoto) creator, Japanese chemist Kikunae Ikeda more than a 100 years ago.

Signs of venom

After 2 years of living my life in such a way that I didn't allow myself to blog anymore, I'm back.

Reading my own old posts is like looking at old pictures, brings back memories of who I was back then. The focus of these new posts has shifted from the original one. The actual inspiration to return came from my never-ending curiosity -that hasn't changed- to answer all those questions that my life experiences give way to, regardless of its nature. Meaning I will be my own personalized Google and Wikipedia.

I've recently moved back to Indonesia, this time to Labuan Bajo in the island of Flores. Living in the tropics has its perks and downfalls. You gotta definitely, among other things, roughen-up. I personally don't think I'm afraid of much, except for certain human-inflicting-damage-on-others situations. 

But let's talk phobias. Among the most feared things by humans are (in no particular order) spiders, thunder & lightning, darkness, dogs, heights, open/crowded spaces, small/enclosed spaces and snakes. Dogs, really?? 

The other day I found a small snake in the bathroom of the house I stayed at the first days. The experience itself was out of this world. When I found the snake, the owner of the house; a small Italian girl with severe Ophidiophobia (new word) couldn't even go into the house, and my boyfriend; an almost 2-meter tall, 36 year-old farm-raised man, hid behind the words "you're from Ecuador, you should be used to dealing with this." So after some very manly 😅 attempts on his behalf, I had no choice but to take care of it myself, thankfully it was a small one so I made it curl-up with a broom, then I put a tupperware over it and with the lid of the pizza box we had the night before, I slowly, but surely picked it up and threw it "far away" back into the green. 
What question rose after the experience? Was it a venomous snake? Which brings me to today's topic:



How to recognize a venomous snake?

First, look out for a triangular shaped head -they say-, in my experience and after seeing pictures, I think the actual shape is more a rhombus or diamond shape, rather than triangular. Most venomous snakes have this head shape, which is characterized by a fat, wide neck, then again, a few don't, plus some non-venomous might also have it. ◊  Mine had it. 

As with most animals, look at that color. There are just colors that scream "you can't touch this". Some are just plain. Mine was black, for example. Some also have special patterns that allow you to immediately recognize if it's venomous or not. 

Snakes are not even aggressive, again, like with most predators they will attack if they feel threatened or are in need. They will go through great lengths to avoid confrontation. If your snake takes an attacking, striking pose, that should be another sign. 🐍  Mine did, after some time of being chased around, patted with brooms or cloths and cornered.

All the other signs are rather hard to look for, specially if you are in a panic over having a snake in your house. Like the eyes, most venomous snakes have vertical eye slits. Most have heat sensors between the eyes and nostrils. Some don't. Either way, I doubt that you will be able to look for these in the moment of the encounter.

As with everything there are exceptions to what I've written here, of course, and he most important thing is actually that you stay calm in such a time rather than start wondering if it will kill you. You can do that afterwards, like I did.
