Tangentially related - it seems there are other things that, if experienced early enough in life, have significant health benefits that are triggered if-and-only-if the catalyst occurs at the right time. For example, pregnancy at a young age is associated with a significant decrease in breast cancer risk. My recollection is this benefit of pregnancy disappears once a women is in her late teens. Our bodies are wildly interesting. https://pubmed.ncbi.nlm.nih.gov/24355762/ https://pubmed.ncbi.nlm.nih.gov/24355762/
