Thank you for commenting @vinamra! Yes, reversing the age and immortality is not the same thing.

I have found fascinating the fact that a species can live indefinitely and change its status back again and again. A lab that managed to capture this jellyfish has found out that in the 2 years of captivity, the jelly fish colony rebirthed 11 times!

This (immortality) is something really difficult to happen in the wild, there are many factors to be foreseen (starvation, predators). However, it does not change the fact that the 'transdifferentiation' can have many implementations in health & life in general.

Thank you again : )
