It is, says zoologist Stephen Proulx, a matter of genetic strength. In April , they had an intimate beachside wedding in Hawaii, and they now have a 6-year-old son, Marek. But he is far more likely to entice female mates than a younger man with a similar sports car. In other words, in our evolutionary past, when people generally pegged it in their twenties, the fact that a man made it to his sixties indicated he must have something very powerful going for him genetically, a trend that still produces biological effects. Share via Email An ageing male flaunting a new Porsche may be the butt of derisive male jokes. Experts say the dynamic makes sense. That is the surprising conclusion of zoologists who believe they have discovered the secret of one of society's most baffling mysteries: Siegner says they bring out the best in each other. Similarly, the reverse process - younger males seeking older females - occurs far more rarely because a woman's fertility starts to decline in her mid-thirties, and terminates in the menopause, researchers added. And unlike his previous flings, Siegner wanted a serious relationship and was straightforward about her desires. Alan Angal says Jennifer Siegner helped him quit partying and get his life together. They are scientific just-so stories that you can use to explain almost every human attribute - from acne to zoophilia. Why not the other way round? It could be all over too quickly. It is the very fact that an older male can still display his munificence that really makes a female's head turn.
