Very strange that the deleterious effects of artificial light extending the day aren't even mentioned. The evidence keeps mounting, we now know that pRGCs exist, but the old assumptions persist. One isolated tribe in New Zealand I believe it was had wonderful health - until a hydro damn was sited there, and they were given free electricity. Diet matters, but light affects appetite, so what you eat will change as your light exposure changes.
