One of the fascinating subjects that I have read about in the recent past is about "Transhumanism".
What is Transhumanism? - Some Definitions
"Transhumanism" is a blanket term given to the school of thought that refuses to accept traditional human limitations such as death, disease and other biological frailties (Src: http://www.mactonnies.com/trans.html )
Transhumanism is an international intellectual and cultural movement supporting the use of science and technology to improve human mental and physical characteristics and capacities. The movement regards aspects of the human condition, such as disability, suffering, disease, aging, and involuntary death as unnecessary and undesirable. Transhumanists look to biotechnologies and other emerging technologies for these purposes. (Src: http://en.wikipedia.org/wiki/Transhumanism )
"Philosophies of life, such as extropy, that seek the continuation and acceleration of the evolution of intelligent life beyond its currently human form and human limitations by means of science and technology, guided by life-promoting principles and values" By Max More (http://www.transhuman.org/transhistory.htm)
Why do I find this subject fascinating?
Individual identity is typically associated with the human body. From time immemorial, there has been a quest for longevity / immortality of the human body.While minor ailments do not have a significant inhibiting impact on our lives, any major illness can severely limit us and thus impact every sphere of our lives – both personal and professional. Also with time and age, there is a degradation of the human body, which imposes limitations on one's physical capabilities.
Imagine a human state where such limitations are not even considerations; A state in which one can achieve longevity, almost synonymous with immortality of the human body. And if science and technology can help achieve this, then the world will be a different place!!!
