    Wrong. And using big words when they are not necessary does not make you right or sound smart btw. “to the knowledge of current science which in its current olfactory capacity” could be summed up as “currently, science”. Brevity and quality of content can show more intelligence than big words like “olfactory capacity”. Now onto my long winded explanation of why you are wrong:

    Everyone has a micro biome on their skin. Each type of bacteria will give off a specific smell. While the populations of bacteria will change over time, the major populations will stay fairly constant, leading to a recognizable smell that each person has. In addition, an amazing amount of chemicals are secreted in sweat. These chemicals not only have their own scent and are determined by genetics, but which chemicals and at what concentrations will encourage/discourage certain populations of bacteria to flourish or not. All of this does produce a fairly static “odor print”. ”Fairly” being key as you are right in that it is not as static or unique as fingerprints (interesting research has suggested that fingerprints aren’t as unique as we once thought but that’s for another Ted talk).

    As for the research, most of the modern research has suggested that it’s actually mostly immune-related genetics that compliment your own (would make a stronger immune system if combine with with yours in an offspring) that your nose is looking for, not just DNA that is dissimilar to yours, which is what it would be if aiming for purely expanding genetic diversity. If this research continues to hold up, you are absolutely wrong in saying it doesn’t play a role in choosing a significant other, and the fact that research is suggesting this at this time makes you completely out of line to just say “this just doesn’t happen.” It does make sense on a genetic compatibility level, as it does in that finding your partner’s smell appealing will factor into your attraction to them. Sorry you don’t find it believable or whatever, but your beliefs do not dictate science.

    Agreed. Can we talk about getting off though? Everyone seems to have their own idea about how to do it and here is my proposal that I am very certain is the most efficient: plane lands at gate, but doors haven’t opened yet. The AISLE seats get up, get their bags, wait patiently in aisle till doors open. The WHOLE LINE of aisle standers files off (they are all ready to just leave), then the next inner seats get up, get their stuff, and file off, etc. Every time someone is “polite” and lets people get up infront of them, they hold up the entire line of aisle standers, and anyone else who could be getting up from their seat and grabbing their things. The entire plane has to wait each time someone says “yes I could just walk forward and leave the plane right now, but please go ahead and take your time getting out of your seat and grabbing your things before I go”
