I will buy Hayflick's book and check it out. I just hope he gives some
references to real scientific publications, or shows results of his own
work. I am very interested in this story. As far as I know, though,
Galapagos totoise cells do have a limited lifespan in culture - they are
not immortal. I have not seen results for reptile, lobster, or fish cells
grown in culture.
