If you define immortality as no age-related increase in mortality rates I gather there are a
number of species (e.g. lobsters) which behave in such a fashion. OK, there are no million-year
old lobsters, but that's because they suffer accidents, disease and get caught by New England
fishermen... :-) But is "no ageing" [which is no increase in mortality rates] the same as
"immortality"? Oh dear, I'm confused now.
