Definitely, lots of babies are born with a 'catch up' fenotype, very interesting. Explaining them when they're adults that their 'hungry feelings' are something they should ignore (and even counter by fasting often) could help them. I study Psychoneuroimmunology and one of my fellow students is a 'catch up' person (for different reasons, but still), and she totally was able to change her relationship with food once she understood what her brain told her vs what her body actually needed.

> I wonder what happens if the cortisol thing is cross-referenced, would there be a correlation?

I think so. Apparently what gives some of the survivors stress is knowing they survived because they had to be a bit of the 'bad guy' by giving up people from their own community, giving them a better chance of survival (not being killed first, at least.)

So yeah, thinking of yourself as a victim or as someone who is okay with knowing that they had to do what they had to do will probably show difference in Cortisol response. Not sure if the research talks about that, just know that explaining people that their 'evil actions' make sense evolutionary speaking (always do as much as you can for survival) showed a lowering stress response.

> unfortunately, most parents are too busy soaking in blue light, while eating sugar, gasping at what they are reading about some random celebrity! :D

Crying! It's so true. Also 'Silent Face Syndrome' (unofficial term for a new phenomenon) is now a thing: where the child doesn't get enough facial expressions/response from the parents as they're staring at their phones. It's a huge stressor for a child who doesn't yet have all the means of communication, and gets a huge part of its brain and even immunological development from literally 'being seen'.
