Geriatrics, Gerontology, & Maintenance

Important Points

  • Geriatrics works on treating pathology – cancer, Alzheimer’s, heart disease – but much too late in the game to extend lifespan.
  • Gerontology attempts to prevent aging by adjusting a very complex system, the metabolism (see picture below). This can have many unwanted side effects. Thus, progress in this field is very difficult.

    Simplified Metabolic Diagram

  • Maintenance and rejuvenation extend lifespan by repairing damage, a process which can be repeated and, itself, improved upon in a parallel process to overall technological progress. All this without altering or disrupting the metabolism.
  • Longevity Escape Velocity (L.E.V.): Even marginal rates of advancement in treatment efficacy can exponentially increase life span when considered over periods in which patients receive rejuvenations every 20 years; each treatment removes greater amounts of damage, more comprehensively.
  • Key Claim of L.E.V.: Eventually our ability to maintain health will hit a threshold at which our medical technology will effectively increase average life span by one year each year (or more). This will eliminate any diminishing returns in damage repair efforts; we will be able to repair more damage in one year than can actually be accumulated during that year. This is what de Grey refers to as “the Methuselarity”.
