In recent culture, technological life extension is considered to be a form of hacking, as 2Dolphins says a “hacker is someone who enjoys the intellectual challenge of creatively overcoming or circumventing limitations — someone who makes things work beyond perceived limits through unconventional means or skills.” In hacking there is also a DIY element too.
There are now 2 broader hacking terms applied for physical life extension technologies: body hacking and life hacking. For first, see my previous post about Bodies in the Making book which handles a diverse range of practices that aren’t usually linked: tattooing, cosmetic surgery, body-building, life extension technologies, self-cutting as exemplars of the body hacking concept. Body hack in that context is something extreme, something very experimental. How extreme form it will take, that depends on the chosen technology. In the old school permalink-free blog Notes from Classy’s Kitchen it is said for instance in the November 26, 2005 post: “What Aubrey de Grey was proposing was the ultimate bodyhack, engineered immortality (or 1000 year life span at least).” Body hack also includes a form a DIY, for instance Nikolaj Nyholm of O’Reilly Radar blogged on the “protocol for “isolat[ing] stem cells from your baby’s placenta in a rent lab or at home” for the upcoming EuroOSCON Make Fest, which also plays well with one emerging theme at this year’s FOO Camp, body hacking — engineers and copper wire paired with doctors, psychologists and neurologists.”
On the other hand there is the emerging life hack movement popularized by blogs as Lifehacker or 43 Folders or Lifehack.org. According to Wikipedia “the term life hack refers to productivity tricks that programmers devise and employ to cut through information overload and organize their data.” And it is also Nikolaj Nyholm, who calls Aubrey de Grey an extraordinary life-hacker concerning his SENS-esque plan to defeat aging. Why life extension counts as a life hack? Long story short: it’s all about hacking time. The narrowest bottleneck of productivity is time, and indefinite life extension’s main ambition is to abandon this final limiting factor, to make time pressure out of time. But can indefinite or maximum life extension (and especially the here supported continuous regeneration treatment through systemic regenerative medicine called Pimm) really be interpreted as a life hack? I think yes. Indefinite life extension is the biggest scale life hack as it amplifies human capacities indefinitely, because it is the only possibility for a human and mortal individual to fully explore his/her own individuality, to develop his/her own abilities let it be mental, physical, or moral.
There is also the term biohacking, which refers mostly to synthetic biology or creating public awareness of human genetic information and in this context biohacker is a synonym for biopunk, and the term is not applied recently to life extension, although in the future it could considering the broad semantic field of the bio prefix.
To sum up: life extension is a form of extreme body hack which is the most extended life hack, although a body hack is rarely a life hack and vice versa. (In the movie Memento Guy Pearce (picture), who lacks short-term memory, uses tattoos on his body as fact memos, which is also a body and life hack, although most tattoos are just ornamental.)
