This story (reported here by the BBC) has been doing the rounds for the past week or two. It's certainly interesting, even if it doesn't have immediate relevance to healthy life extension research. Examples of natural healthy longevity - extreme longevity in this case - in the animal kingdom are an open invitation to study the biochemistry and genetics of these species. By doing so, we might gain further insight into how best to fight aging in humans. At the very least, those who decry longer, healthier lifespans as being unnatural can be pointed in the direction of the very natural and very long-lived red urchin.
