Ageless Quest: One Scientist's Search for Genes that Prolong Youth
Ageless Questis a personal, sometimes controversial, account of the pursuit of a genetic ‚€ ̃cure' for aging by an expert in the field. The author is the Novartis Professor of Biology at the Massachusetts Institute of Technology. Aging has always been regarded as a highly complex process with many degenerative changes leading to the cessation of life. But recent research has identified a relatively simple mechanism that governs the pace of aging. Lenny Guarente's Ageless Questis a scientific detective story for the baby boom generation. It offers an insider's view of an area of potentially astonishing high reward‚€”and equally high risk.

Page 78 - My proposal in 1971 was to forecast travel demand at the level of the individual rather than at the level of the traffic zone.
Page 122 - Usually at least one of the board members "attends" by conference call. The meeting is an orderly discussion by voices near and far about pressing matters, usually involving the financing and business development of the company. This is what was missing at my earlier start-up, BioTechnica. We also talk about the latest science and the research directions of the company. At the end we leave the room feeling good, and, if the stars are aligned properly, proceed to a fine restaurant for dinner.
Page 119 - Cindy convinced us that the hidden assets of VC backing are invaluable to the success of start-ups. They have many contacts with other companies and boundless experience to bring to the table. Furthermore, their backing is an imprimatur that will attract more investors as the company grows. Finally, they are ready to invest again in a later round of financing.

Page 40 - A few weeks later, the rDNA circle model of aging appeared on the front page of the New York Times science section accompanied by a long article by Nicholas Wade, the science reporter for the Times.
Page 122 - I still do not know the answer to this question, but I am optimistic that the two can be kept separate and complementary rather than competitive.
