[ExI] Maximum biological lifespan

[David Lubkin]

Do you see any inherent maximum active lifespan (that is, not in a 
dormant state like a spore) for an evolved biological being? How 
about for a conscious evolved biological being (that is, with 
considerations of memory formation)?

For instance, could there be a planet somewhere that naturally 
developed a single, continual consciousness that has lasted a 
thousand years? A million? A billion?

By naturally developed I mean to exclude a being that became so 
long-lived through its developing life-extension technologies.
