Omental Tissue is found around the Spinal chord, and contains useful healing materials (see http://www.healingtherapies.info/Omentum.htm and http://www.neurologyindia.com/vol50-1/FullArticles/cr-1.pdf ).

It has been reported that transferring a bit of the omental tissue to the affected part - so far, the brain (for epilepsy?) or the spinal chord (for a broken back) - can help healing.  Not cure the ill, I note - but help healing.  

This technique actually originated in India, but is as yet unknown in the USA or the West because no scientifically rigorous investigation has yet been done on the results of the surgery.   But results have occurred, but have not yet passed the "anecdotal" stage.

My own reply to this at the time, was...

It made a good point about pensions and living until well past the centenary.   Pensions arte basically a form of life insurance, and will be blown to pot by a change - an extension - in life expectancy.   For a male in Britain this is currently 76 or 86, I forget which.   Pensions are paid for, now, largely by the contributions of younger (wo)men as well as by the
capital earnings of a largew fund.   This would increase dramatically, plus the size of the pension (for existing pensioners) would be made smaller.
Like hell!   I'm practically there myself - and I know what I'd say!

But that's the long-term point;  about the smaller-term point of a cure or relief for the ills of old age, that could be different - if the final death point didn't change.    After all (ignoring that bit about lengthening chromosomes) stem cells et al. need damage to work;  they are not general improvers.   So the generalised reduction in efficiency of the brain and other cells will be maintained, and the final death becomes a relief rather than as dread (ask my father - now an novogenarian and longing for death to end the marvellous life cycle he's had).   To change aged cells into more youthful ones sounds like utopia - but.... (i) too many people living on too little facilities that the Earth offers;  (ii) incomes will DROP as pension pay-outs increase, so quality of living will drop for all, and for the elderly in particular;  (iii)  Thus ican see the life cycle being closed again, not by suicidal means but simply by more voluntarily letting it happen.

Any comments?  This could be the debate of the  future...
