Length of a Generation & Longevity

I was watching one of the science digest programs the other day and there was an interesting piece on longevity. According to a new theory, delayed reproduction results in greater lifespans of the children. Female mice were prevented from having early pregnancies and their offspring had significantly longer lives. There also seemed to be a cumulative effect over multiple generations.

I previously thought that the lifespans of ancient royals was limited to about 70 years because of excessive alcohol consumption. But in the race to gain dynastic advantage, royal women typical conceived very young. It might make sense that this practice effectively limited the royal lifespan. It might also explain why there was a memory of even more ancient people having had extraordinary longevity. Because of competition this "secret of immortality" may have been lost. Something to think about anyway.
