It has been apparent for some time that certain species of animal have extremely high maximum life spans. Researchers have been looking into this, but - as for most areas in aging research - there is comparatively little funding for these sorts of studies. The Ageless Animals website presents some of the more interesting scientific work on animals that appear to age very slowly. It makes for interesting reading. While this research may or may not uncover information of use to healthy life extension in humans and other mammals, it demonstrates that complex organisms - like humans - can live healthily for longer than the present day maximum human life span.
