> So something whose lifespan is exponentially distributed (such as a radioactive particle) does not display the Lindy effect. Huh? Is this true? If I had particles with unknown half-times, I think I would expect the older particles to stay around longer, if that makes sense. (It is possible that there is no 'I expect' in the probability theory sense, like in the two envelopes problem.)
