Rejuvenation Biotechnology

Because untreated aging leads to frailty, cardiovascular disease, brain disorders, and death, we need rejuvenation biotechnology to reverse the aging processes and thereby restore youth and health.

As explained on our What is Aging? page, aging consists of multiple processes (“hallmarks”) that gradually cause harm and lead to age-related disease. Most products marketed as “anti-aging” or that purport to “rejuvenate” the body do not actually address any of these hallmarks and cannot affect the root causes of age-related disease; therefore, they are not rejuvenation biotechnology.

Rejuvenation biotechnology is advanced medical technology that directly addresses any of the various aging processes in order to restore tissue and organ function to a more youthful state, thereby ameliorating, delaying, or preventing age-related diseases.

Some people describe rejuvenation biotechnology as “life extension”, though this description while somewhat accurate is the subject of considerable misunderstanding and incorrect assumptions. The Lifextenshow team have created a whole series of informative videos about life extension and the hallmarks of aging which you can enjoy below.

Ultimately, the goal of rejuvenation biotechnology is to make chronologically old and chronologically young people, at every physical level, indistinguishable from one another.

However, no single rejuvenative therapy will completely restore someone to a youthful state. Because the causes of aging are so broad and interlinked, rejuvenation biotechnology must be as equally broad and comprehensive to match.

For example, senolytics are rejuvenative because they eliminate harmful senescent cells, which accumulate with age and are one of the proposed hallmarks of aging. However, because types of senescent cells differ from one another, a comprehensive suite of senolytic therapies is required to directly address this particular hallmark through destroying these cells. Stem cell therapies are rejuvenative because they address stem cell exhaustion, restoring the body’s youthful ability to repair tissues; however, because the body requires many types of stem cells for long-term function, each stem cell niche must be replenished. Finally, therapies that boost or correct the failing immune system can address altered intercellular communication or stem cell exhaustion depending on their exact use.

Because each hallmark requires intensive effort to comprehensively combat, it is clear that building a complete set of rejuvenation biotechnology therapies will require a great deal of research and development. Creating this technology will require help from investors, medical professionals, researchers, policymakers, and members of the public. Poor funding is one of the four bottlenecks of the development of rejuvenation biotechnology.

Of course, creating a world with this technology is not going to be without its challenges and from time to time people raise concerns about longer lives which we have considered and have responded to some of the more common ones.
