I also know a great deal about art, and can use that in many situations. Or history. SOME science... Yeah, little about a lot helps, but i always strive to learn more :)
A. you're REALLY bored.
B. You like mixing a little Metaphysics with Biology
or C. are really REALLY bored! lol
This should actually go under the "Things I Think About" section, but it really works better here. I was watching documentaries on Netflix one night, and there was one that came up on Phillip K. Dick. and it started making me think about perception. Not anywhere close to his realm if you are familiar with his work, but perception in general.
So.... to answer the question, I think on some level we all look at people, see their body language, their clothing, their physical demeanor, hight, size, age,gender or any other way their physicality can be noticed... the brain processes this information based on what the brains "know" (ask about that seriously, and all tell you about my thoughts on nature vs nurture! so be warned! lol) and boom the conscious mind picks up on a detail! Facial features represent amounts of hormones in a person. Testosterone equals a square jaw, just think of Disney "tough guys" as an example. Our biology tells us to make the best offspring as possible, so if testosterone in high levels would help or hinder that, it would factor into what we notice in another person.
And that's only if you can see the person. Their voice would have a similar reaction in the brain. How deep is it? Is their an accent. Are strange terms being used? Etc. Subconsciously, the brain would "know" things about another person from their manner of speach. Are they high brow, down to Earth, educated, ignorant, etc.?
Then theres the sense of scent. How pheromones effect us is unreal! Did you know studies have shown that basically, the difference between "musk" and "B.O." is based on our immune systems? No kidding, if a person has a immunities to some things you don't, then the other person smells good to you! And those scents are extremely powerful in how our brain assesses a person, but we're not even aware of them. I've even heard that sweat from heat and the sweat from stress smells differently to some people.
Now, animals process the tangible without prejudice, or at least very little amounts of it. But we are different. We have a mind, a consciousness. And that processes the same information differently. We know the basics, if as a kid, this happened to you, than you do that as a response. So That messes with the subconscious to.... well basically make a big mess.
Therefore, my answer is-
What people first notice about me is what they first notice on a fully conscious level after the conscious and unconscious battle it out. So it's different for every person. Therefore, I have no freaking clue what people first notice about me! Yep, that's called a long answer to a short question! lol.
Yes, this answer says more about me than the question asked lol
Movies: Star Wars, Star Trek, Starship Troopers (actually my favorite movie to be honest), Boondock Saints, Zombie flicks, Most of Kevin Smith's movies, Comic book movies, Horror, scifi, and many many other's, you'll just have to ask if you want to know.
Music: Rock mainly, but there's a select few rap, R&B and country songs I don't mind listen to, I must admit. Oh and Weird Al is a musical/comedic Diety!!! I also enjoy many songs from the 50-70's
Food: Don't know my favorite food is. I like a lot but don't like a lot, so hard to put 'favorites'
