Dr Bloom spoke about how your overall mood during college is a good predictor for how happy you'll be as a person throughout your life. He talked about the optimum time to get married is 26. He elucidated the idea of your prefrontal cortex solidifying around 25, making personality changes MUCH more difficult.
Dr Sopolsky spoke about biological markers that may affect human behavior - both inherited and environmentally influenced.
At 35 I am starting to suspect that I may be on the spectrum ( I kinda expected some adult to tell me this as a child, if it's true ).
The males on my fathers side (with the exception of my uncle) do not make it past 67.
My mothers side has inter-generational trauma that I know i've inherited avoidant behaviors that limit my social ability.
So great news.
