Very interesting, where can I read about this?  Why was the oxygen supposedly
higher?

Also, anyone know if those reduced caloric diet animal longevity studies
included studying offspring to see what negative or positive effects would
occur long-term.  Like are the kids of these long-lived animals healthier or
weaker, meaning positive evolution, or a dead-end?
