Perhaps everyone knows this ,,,,,,,,,,,,,,
As a relatively infrequent vistor to this board it seems alot of the posts involve cancer treatment and I gather everyone knows cancer cells contain a telemerase which restores the telemeres after division conferring immortality.
From an aging point human cells can be divided into three types, those who virtually never divide eg. nerve cells, those who appear to have unlimited ability to divide,eg epidermal cells, and those with a limited number of cell divisions, mesenchymal eg, fibroblasts, muscle, fat. In this last group the number of divisions is determined by telemere length. Of the three cell types some current theories of aging feel it is mainly a problem in the last group. The telemeres representing a biological clock. IMHO there is little question that changes in number of connective tissue cells are responsible for most of the visual changes seen in aging appearence.

I first became aware of Geron sometime in the nineties. I am not currently a shareholder. My intro was via Dr Judah Folkman
of Boston Childrens etc. Dr Folkman has always been considered one of HMS's brightest. I believe he was working with GERN on his tumor angiogenisis at the time. If you are focused on cancer I can see how you might look on telemerases as bad things. However they could contain the key to retaining youth. Understood there is much more we don't know about aging than we do.
If you ask almost anyone you meet,," can aging be halted"? They will tell you "No it is impossible". But remember a hundred and a few years ago if you ask anyone "Can a flying machine be built"?, They also would have told you, "no it is impossible."
We can not at this time say it is impossible to halt aging. We can only say no one has been able to do it so far.
