There are species that have no aging -- Hydra for example -- but they do it by not having a nervous system -- and not having any tissues in fact that rely for their function on very long-lived cells.
Exista specii care nu imbatranesc, cum este Hydra, dar secretul lor este ca nu au sistem nervos si nici vreun fel de tesut care sa se bazeze pentru a-si indeplini functiile pe celule care traiesc mult.
