Why do we have to die? in terms of ordination I wouldn't know one
way or another- it just seems to be the way things developed. I do
point out ,however, that the brain seems to have a finite capacity.
Granting this, significantly increased longevity might require
periodic "flushing" or additional input of cells and neural
connections. Failing this the individual would eventually become
incapable of assimilating information. Thus out ability to use out
cerebral cortex wouls be limited severely in time.
