The talk has 2 parts: 1) stories on infidelity and 2) stories on long living. I present stories on interesting dynamics of extra-pair (group) mating in two species of sparrows: house sparrows and hedge sparrows (aka dunnocks).

Then, in the second part, which is completely unrelated to the first part (unfortunately), I present 3 metaanalyses which investigated how to live long. And I should be able to give my audience on some advice on long healthy living! [more]
