"Our goal for this project was to produce a report about the complex processes involved in ageing. We wanted it to be accessible to a wide spectrum of readers, not just those involved in academic study. It has been an important example of teamwork - bringing together Panel members with their different disciplines, the eight scientific experts, a leading social research organisation, medical writers, actuaries and modellers, among others. This report is based on the opinions of leading scientists who have been studying the biology of ageing. We have supplemented their views with some key evidence from the results of recent research into ageing, and have developed a model to illustrate what the impact of different treatments might be on our lifespan. It is being published because the Panel is keen to share its conclusions with others and to support the continuing debate regarding the implications of ageing. In addition, the Panel is very keen to hear from others working on any related research which can aid understanding and be recognised in our future work."
