Television

"There is not the slightest doubt that light taken through the eyes affects the cells; there is no doubt that variations in light spectra cause variations in cellular activity; there is no doubt that sitting and looking at television light affects our cells in some way. But no one can say how, and not many are asking." (p. 191)
