ISTR that the delay from the time a photon is generated by fusion to
the time it actually gets out of the photosphere of the Sun is O(800
years). I.e., that sunlight outdoors today was actually generated
about 1200 AD.

But is it really the same photon? How can you tell? (Can't label 'em!)

That's a good question. I'd say "no", but the physicist who wrote that
bit seemed to think it was.
