Does light have an infinite lifetime?

In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?

Photons would have to experience time in order to decay, but we know that they do not because they travel at the speed of light. It's impossible for anything moving that fast to experience anything.

If photons experienced time, they would be unable to travel at the speed of light.
