Frédéric Bastiat coined the phrase:
What is seen and what is not seen
While I was obese and suffering from insulin resistance and the many ailments that it induces I was also degenerating in less obvious ways. I had to have new glasses every couple of years and lots of visit to the dentist to treat caries. Then I lost weight and the ailments reversed. I have not taken any drugs for the past ten years or so.
What was not seen is that I haven’t had caries or the need for new glasses for a very long time, maybe a decade or more. The accelerated degeneration stopped! Now I’m just getting older.
