 Well, you know, we really are light beings and we emit biophotonic energy in our biofield. This is measurable. What's interesting is that when we're really stressed, so when our vagus nerve is on that high charge, we leak more light. Mitochondria doesn't work as well. Our digestion doesn't work as well. So all of the aging mechanisms sort of get set off in that stress immune response. So when we feed ourselves with light, sunlight is ideal at the right times, of course, very early morning and in the evening. And just to have a practice of bringing in that light, that's very nourishing.
