possibly just made up, but if you think of all the diseases we didn't have yet. bacteria that wasn't yet crawling all over and inside us. plus a million other potential variables. maybe something would make sense. there's a lizard on and island off new zealand that is said to live about 250 years or more. meanwhile some insects live for 24 hours. hard to say what could have happened that far back.  in any case i still think it's most likely some fiction or urban legend. if we're lucky though it's true and maybe ai and research will extend our lives before we croak at a "normal" age. at least if we don't all die from global cooling before then.
