I do not buy the story even if several Universities think so. 
evidence is too weak.

Okay...you have a point.

But let me.explain my thinking. 

Until 10yrs ago certain Cancers were incurable, say stomach cancer or blood cancer.

Scientist tried compound by the thousands and find one that unlock a cure.


When the compound is found the cancer goes from terminal to treatable and patient can survive.

Similarly, ageing may be treated by some compound could be a rare herb or something.  Just like cancer it is all genetic. Because Chinese medicine is trial and error over thousands of years could have secretly found a herb or compound that changes lifespans.

I am just saying it's possible...I am.not saying it is true. Just that such a compound van exist in nature or by human synthesis.

This compound cannot be common because if it is there will be many 200yr olds walking around.
