I dunno.
But they are clearly looking at the problem at several levels.
As far as I understand the science, an anti-ageing procedure taken for the first time in (say) your twenties would effectively stop you ageing, possibly making you look even younger. There was also a possibility that such a treatment taken even later in life would still make the body "younger".
IMHO, such "immortality" would give a longevity very similar to that of elves in popular fantasy novels (e.g. those of Katherine Kerr or Raymond Feist).
