I wonder if UV light is mentioned? When I was a kid, our schools had these big banks of windows in every classroom. The main purpose for them was to reduce the amount of lighting that was needed. A side benefit was that the entire room was bathed in UV light, which kills viruses and bacteria. Then in the mid 90's all of those windows were replaced with ones that have UV filters because of the minute possibility that little Johnny or Janie might get skin cancer.
