Leonard Hayflick and 50 Cell Cycle

Cell Cycle Events 

1. Man and many advanced animals have 50 cell cycles in their life time.

2. Up to 42 cycles are used up by the age of 18 months of age.

3. About 42 to 45 are cycles are consumed by about 15 years of age.

That means for puberty 3 cycles are used up.

4. After puberty one is left with only 5 cycles.

3. There is a condition called progeria where babies are born in advanced stage of cell cycle and rapidly age and die young.

4. If we take a somatocyte from (with mutated genome) a case of this condition one can modulate few more cell cycles to be advanced by culturing under correct conditions with sexual maturation and bald head.
