Jmcll, - this question someone asked yesterday during Shareholders meeting , and Dr RP answered ,

one week in mice is 1 year in human..

This is really impressive , so when our mice lives 9 weeks it is 9 years in human , and 19 weeks will be 19 years ...
Hopefully we all will die due to old age ...

And someone asked if true that if medicine prolong life for 2 months FDA will approve it , Dr RP answered , Yes ...

Sorry I read again your question and Plavac answer of about 90% is imo accurate ...
But I still will leave my above answer , since imo it is also very important to know ...
