I am not really thinking in terms of how molecules interact. I am thinking in terms of how to convey the means to avoid exposure to germs/toxins/etc and also how to convey the subtle cumulative impacts of dietary choices. I think many people prefer pills to dietary changes because the difference a pill makes is readily recognizable whereas dietary impacts are far subtler and easily overlooked, thus not really taken seriously by many people. I've made substantial changes in my body chemistry, in part by micromanaging my diet. This has (apparently -- by observation) made changes in things most people think can't be changed. They need a more explicit mental model and I need a more information dense means to convey my ideas and experiences. The written word on my website is just not adequate to the job.
My ex was career military, so I am familiar with the fact that they do this sort of thing. It is one reason I take it seriously as a potential educational medium: The military has some very solid practices, in part because lives are stake. Similarly, lives are stake with health issues.
That is interesting. I know the military is trying this. They have a limited amount of time to teach a larger and larger amount of things to new recruits. They are experimenting with VR environments.
But I can see how that could be applied to other things. Perhaps a sim environment that lets someone see how molecules interact.
