> A new study could change that. Researchers have identified an odorless compound emitted by people—and in particular babies—called hexadecanal, or HEX, that appears to foster aggressive behavior in women and blunt it in men. Hexadecanal is a sixteen-carbon chain aldehyde: https://en.wikipedia.org/wiki/Hexadecanal https://en.wikipedia.org/wiki/Hexadecanal A few years back a team claimed to have isolated essence of old person, 2-nonenal, a chemically-related nine-carbon unsaturated aldehyde: https://en.wikipedia.org/wiki/2-Nonenal https://en.wikipedia.org/wiki/2-Nonenal https://www.jidonline.org/article/S0022-202X(15)41198-4/fulltext https://www.jidonline.org/article/S0022-202X(15)41198-4/full... The occurrence of pheromones in the animal kingdom, but so far scant evidence in humans, is a puzzle: https://www.scientificamerican.com/article/are-human-pheromones-real/ https://www.scientificamerican.com/article/are-human-pheromo... Maybe there really are no human pheromones. Or maybe they're just really hard to study because studying human behavior is so hard in general.

Hexadecanal appears to be an approved food additive that you can buy in bulk?

  Maybe because it is in a lot of foods naturally? https://foodb.ca/compounds/FDB003048#associated_foods https://foodb.ca/compounds/FDB003048#associated_foods Supposedly, it tastes like cardboard.

> Maybe there really are no human pheromones. There are human pheromones, but the church has taught its followers to clean themselves for hundreds of years, just by observing behaviour. Today we have science which can explain behaviour and different chemicals do affect behaviour. Just takes loads of histidine and see how snappy and aggressive you get, or take loads of glycine and see how you laugh your head off in stressful (cortisol high) situations. I've wondered for some time why vitamin RDA's are set at the levels they are considering the world is a more polluted and stressful place. My conclusion so far is the current vitamin RDA's will not give you rude health and I think there is some behinds the scenes military involvement or troops used as unwitting guinea pigs to help govt's decide what vitamin RDA levels should be. Its very hard to get healthy food today despite all the technology, a lot has changed since the 70's.
