This isn't just wild ramblings, there have been huge steps made already. I have watched a lot of documentaries about this topic. As you get older (I am nearly 50) the question of longevity becomes a more burning issue.
The human genome is nearly fully mapped, they have already identified many of genes that cause ageing, it is possible to alter these genes with DNA therapy, in experiments they have already doubled the life expectancy of mice. On all of teh programmes I have watch the consensus has been that in approx 20 they will be able to halt and possibly reverse ageing.
But it does raise lots of questions, both ethical and practical, if we live longer, even if we just double the life span of the average human it will have a devastating effect on human population growth, it is not sustainable on this planet. So would everyone give up the right to have children? I doubt it, it is our most basic instinct to breed. resources would be stretched beyond breaking point and of course that then leads to wars
And who would get this treatment? Not the likes of you and me, it would be reserved for those who have the so called greatest minds (insert the word Rich here) Do you think they will go too the housing projects in America, or the council estates in England shouting "Hey, who wants to claim social security payments forever?" We will end up with an even more unfair fractured society, civil unrest, riots etc.
They should realise that just because you can do something, does not mean you SHOULD do it
