Humans can glow under special circumstances. The blood of smokers is weakly chemoluminescent, and I read a report in a nineteenth-century text that dying people sometimes shine. Modern researchers have found that several mortal conditions make human blood give off even more light than that of smokers, so that may be what is behind those old reports. But in general we can't produce living light [bioluminescence]. An enormous number of other organisms - plants, animals, bacteria - can, however. Perhaps that is why we are so fascinated by the light.
