You've Got That Glow ...

I’m not going to try to read your aura, but researchers at University of Calgary in Alberta, Canada have shown that living creatures do give off light. Mind you, it’s very weak—too dim for humans to see—but it does end when the creature dies.

The cause involves chemistry: specifically, animals’ use of oxygen to produce energy. A byproduct of those reactions is reactive oxygen-containing molecules. Too much of them causes stress in living cells, which respond in a way that can release photons.

That’s a very abbreviated description, but you can read more details here: https://www.msn.com/en-ca/news/technology/humans-give-off-a-light-that-is-extinguished-in-death-study-reveals/ar-AA1FMZa9

So you are a source of light in the world!
