The learn and earn challenge has become my favorite part of steem. Of course, the challenge created by 
What did I learn yesterday?
It quickly became my favorite thing to write down in the morning. Just couple of words. Usually between 3-6. Just keywords. The realization that I'm waking up smarter than yesterday just totally boosts the energy for the next day.>
1. Orthotropics
From what I understand, our entire skull is essentially held together by sutures, its not a solid unit. It clearly doesnt have the mobility of a joint, but it seems the posture of your tongue will change the structure of your face over a period of years.

So it seems the position of your Maxilla and Mandible is directly related to how attractive you are and your tongue is used to push up into the roof of the mouth to push the maxilla forward. It also pushes the teeth forward to prevent crooked teeth.
Orthotropics is a science used especially on young children but can also be used on adults, check out the example below.

2. Cyclone Idai in Mozambique
The storm made landfall near the port city of Beira on Thursday with winds of up to 177 km/h (106 mph), so far the death toll is estimated to be around 1000.
3. What does it mean to be non-binary ?
I've heard the term before but I never gave it much thought. I somehow associated it with being a transgender person but I think that's not exactly the same thing.
Non-binary
adjective
adjective: non-binary; adjective: nonbinary
. 1. not relating to, composed of, or involving just two things.
"Aristotelian ontology is non-binary on the second level in that it allows for degrees of being"
- denoting or relating to a gender or sexual identity that is not defined in terms of traditional binary oppositions such as male and female or homosexual and heterosexual.
"the novelist identifies as non-binary">
If a person identifies as non-binary, it means that they feel their gender is somewhere in-between being a man or a woman, orthat it goes beyond either of the two. They can also feel like they have no gender at all, and these feelings may fluctuate so it may be permanent or only some of the time.
There are apparently no end to the amount of 'genders' one can associate with, as you can imagine, the rabbit hole goes pretty deep..
How do you address a non binary person?
It seems most of them are okay with "they" or "them" but there is an extensive list of examples of which I cant list all of them but if youre curious you can check it out here
