What is the maximum duration of human life?
Since 1974 I have had the possibility of living for the rest of eternity.
As I completed my undergrad biochem studies it became clear to me in logic that we are programmed to die, and that the default mode for cellular life is indefinite. Our germ line is part of an unbroken chain of cellular life. Our somatic lines die.
That being the case it became clear that a 5 stage process was required.
1 decode the genome (done over a decade ago).
2 develop a system that allows us to model 3d protein structure based on RNA sequence.
3 develop sufficient understanding on molecular interactions to be able to make useful models of intracellular activity.
4 model all key factors leading to cellular senescence with age.
5 develop effective counter strategies to first block then reverse age related loss of function.
We are at stage 3 in that process and the rate of progress is accelerating, so I might just make it.
Once we get past the medical issues, and get substantial technology personalised, those who wish to ought to be able to implement risk profiles that give a reasonable probability of living a very long time.
