Brain and Longevity

In this third volume on longevity Fondation Ipsen has again collected the most recent results in research on genes and diet in the evolution of human longevity, educational level and longevity, cognitive impairment and survival at older age and other contributions. The preponderance of relatively short - compared to long-lived organisms suggests that morphogenesis is easier to accomplish than is maintenace of soma, whereas the broad range of longevities of organisms demonstrates that maintaining soma for extended periods of time is possible. The underlying assumption of "disposable soma" theory of aging is that the expense of maintaining somatic cells depends on their contribution to the welfare of the germ cells.
