There are many other health devices that are (likely) obviated by proper health status in life, and maybe more importantly, in utero. Two that come to mind that affect me are glasses and braces.
For myopia, there is weak evidence that it is caused by lack of sun exposure at an early age.
So, you can blame your parents for giving you a bad diet low in fat soluble vitamins in your childhood, and not making you go outside. Other than that, you can try to prevent it in your own children.
As for myopia the effect is probably due to some combination of lack of very bright light exposure and a infrequent need to focus far away or too much time spent focusing close without breaks. As you say the solution is to spend more time outdoors as a child, and alternate relatively shorter sessions of desk/screen work with more active interludes, making sure to glance around the room with some frequency.
Also note, as i stated: "intentionally or not" It doesn't matter what the intent was when lies are spread. The end result matters.
And walterbell is exactly right. Would love to see an answer to that.
