Understanding the relationship between frailty and longevity becomes increasingly important as the world continues to age and life expectancy in most countries continues to increase. The articles contained in this book are the outcome of a colloquium sponsored by Fondation IPSEN in which interdisciplinary perspectives were brought to bear on conceptual, empirical and clinical aspects of this relationship.
