immortality who wants to live
Immortality is a popular topic in fiction, as it discovers mankind's deep seated fears and
comprehension of its own mortality. Immortal beings and species are plentiful in fiction,
specifically fantasy fiction, and the meaning of "immortal" tends to differ.
Biological immortality refers to a steady or lowering rate of mortality from cellular senescence as a
function of chronological age. Different unicellular and multicellular species might achieve this
state either throughout their presence or after living long enough. A biologically immortal living
being can still pass away from ways apart from senescence, such as through injury or condition.
Biological kinds have fundamental limitations which medical interventions or engineering might or
may not be able to conquer. Natural selection has established possible biological immortality in a
minimum of one species, the jellyfish Turritopsis dohrnii.
Physical immortality is a state of life that enables a person to avoid fatality and preserve aware
idea. It can suggest the unending existence of a person from a physical source apart from natural
life, such as a computer. Active pursuit of physical immortality can either be based on scientific
trends, such as cryonics, digital immortality, breakthroughs in rejuvenation or forecasts of an
impending technological singularity, or because of a spiritual belief, such as those held by
Rastafarians or Rebirthers.
Technological immortality is the prospect for much longer life spans enabled by scientific
advances in a range of fields: nanotechnology, emergency clinic procedures, genetics, biological
engineering, regenerative medication, microbiology, and others. Contemporary life spans in the
advanced commercial societies are currently significantly longer than those of the past because of
much better nutrition, accessibility of healthcare, standard of life and bio clinical scientific
advances. Technological immortality forecasts more progress for the same factors over the near
term. An essential facet of existing scientific thinking about immortality is that some combination
of human cloning, cryonics or nanotechnology will play a vital role in severe life extension. Robert
Freitas, a nanorobotics theorist, suggests tiny clinical nanorobots could be developed to go
through human bloodstreams, discover hazardous things like cancer cells and bacteria, and
destroy them. Freitas anticipates that gene therapies and nanotechnology will ultimately make the
body successfully self sustainable and capable of living indefinitely, short of extreme brain
trauma. This supports the theory that we will certainly be able to continually produce biological or
artificial replacement parts to replace broken or dying ones.
Since immortality is seen as a desire of humanity, styles involving immortality frequently discover
the downsides as well as the benefits of such a quality. Sometimes immortality is utilized as a
punishment, or a curse that might be planned to teach a lesson. It is not uncommon to discover
immortal characters yearning for death. The quest for immortality is fraught with hazard at lots of
levels. People enjoy the romantic concept of living for life, however they fail to think about the
effects of what could happen to our species if, undoubtedly, immortality was cheap and obtainable
by the masses.
