Barring the Hayflick limit, in time this will no longer be a limit, as cell pathology can and will eventually be reverse-engineered. Thus the Hayflick limit will have to adapt new boundaires and in time, be completely phased out.
The answer is will come from Cell Therapy and the implementation of Telomere "blocking".
As a cell divides, the telomeres shorten respectively. Once the telomeres are shortened enough, cell division completely cease and the cell dies. When enough cells die, we die.
Bacteria and Cancer cells do not suffer from not being able to divide, due to no constraints on telomeres. They can divide Indefinitely.
Just a side note..........All you Steroid users are effectively SHORTENING your TELOMERES at a more rapid rate and also increasing T3 production. Hence you are aging yourselves prematurely in all areas. This speeds up Cell Pathology.
Also, you FAT people(Zach Gates, MisterMAgoo) are enacting this process as well by the increased consumption of energy.
Hope this helps.
