I am fascinated by the fact that 18 parts of the brain, that we know of, emit light. And then you look at religious icons and they are often depicted emitting light around their heads (halos) from Jesus to Buddha to angels. They are also called enlightened! Also, 93% of the mass in our body is stardust! Wow! Weird, but cool. Pregnant women "glow" and really happy people seem to be "beaming" with joy, etc. :)

And to dust you shall return.” Genesis 3:19
