"When we're children, our brains are much more flexible and malleable in terms of we haven't really formulated our beliefs about ourselves or how the world around us operates. They're really, really flexible. But as we get into adulthood, our brains become more rigid and we become much more solidified in those beliefs, and it's hard to change them.
When we're on a psychedelic, our brains become much more flexible, or entropic; we get back to that state of childlike wonder and awe.
I think that that shows a lot of promise in terms of how and why it seems like psychedelics are having some promise for PTSD, other types of trauma, depression, anxiety, negative beliefs about your body, all of these things are being studied right now."

Psilocybin delays aging, extends lifespan,
new Emory study suggests
A newly published study demonstrates that psilocin, a byproduct of consuming psilocybin extended the cellular lifespan of human skin and lung cells by more than 50%.

Psilocybin microdosers demonstrate greater observed improvements in mood and mental health at one month relative to non-microdosing controls
July 2022
Experienced microdosers often experiment with many different protocols and frequently cite advantages and drawbacks to each method; some claim that supplement stacking is a more robust and effective protocol for cognitive function and promoting overall mental health. For those interested in contributing to the body of microdosing research, an experimental app called microdose.me has been developed in collaboration with the health research company Quantified Citizen and the Canadian arm of the Multidisciplinary Association for Psychedelic Studies (MAPS).
