would it be possible to come up with a universal measure of ageing for cars? Not universal or at least not easily or affordably. I can test each critical component and get a pretty good idea how much stress that component has been exposed to. Maybe the same could be done with mammals and we just test the critical components to get some numbers then apply a rough estimate of a score. Then perhaps a formula can be applied to the set of scores from all the critical components to assign a health score. I am considering the concept perfect is the enemy of good in this case.
