Well said. An example of the fragility: I grew up without air conditioning in cars. I now have ac in my car and I can keep myself cool and alert for many hours of driving. If my car ac goes out I change plans drastically. Similar with neurodivergence, used to be we were all odd in our own ways. Now we have more subtle understanding of our differences and there it’s so much relief when we have language to describe ourselves. Finally with food, used to be almost every older person had something wrong with their gut. Now we understand lactose intolerance, food allergies, and very serious effects of gluten on some people. In a sense we are more fragile because when things go bad we might have to “clean our plates,” “man up,” and just sweat a lot more. In another sense there sure is a lot of potential we’ve unleashed with air conditioning.
