The Voice of Reason: a Quarter Century of Fighting Aging

I’m pleased to announce the release of The Voice of Reason, a new book based on the writings of Reason. His website fightaging.org has for decades followed the progress in medical technology to treat aging and also advocated for more time and attention to be devoted to the field.

Reason is well known in the community as an advocate, but he is also an investor and operator in the space. His company Repair Biotechnologies is developing a therapy to treat cardiovascular disease, the number one cause of death in advanced economies.

This book collects the best of his 20,000 posts and organizes them around major themes like the nature of aging and ways to treat it. I hope you find it useful, entertaining, and, above all, motivational.

The Best of Ben Best: Selected Writings on Cryonics, Aging, and the Examined Life

I’m happy to announce the release of The Best of Ben Best, a new book based on the writings of Ben Best. His website benbest.com has long been a rich source of information for anyone interested in cryonics and longevity. This new book contains a selection of writings that weave together the related science and Ben’s personal anecdotes.

Ben Best is well known in the cryonics community and is a leader in the field. He is so prolific that it can be challenging for newcomers to navigate everything he has written. This book not only serves as an easy introduction, but also an index into his complete works.

I should also mention that Ben did not choose what was included in the book, so any faults lie with me. If you recommend any changes, just let me know.

Radical Life Extension: Technological Strategies to Defeat Aging

Today I’m releasing a new book called Radical Life Extension. It explains what aging is and explores technologies that could help slow or reverse the process. Aging is the leading cause of death, so it is a very urgent and important problem, assuming something can be done about it.

People have developed a number of strategies for extending human lifespan. Most of them won’t work, but a few strategies stand out as not only possible, but feasible within the lifetimes of people living today.

The current best contenders are biostasis, replacement, and advanced bioengineering. Biostasis means pausing the death process with cold temperatures or chemicals so that someone might be saved by future technology. Replacement means getting cell and organ transplants to rejuvenate the body. Bioengineering means using powerful gene therapies to rewrite human biology.
