The Pattern in Longevity and how to break free

It has been recently announced that plants' lifespan follow the same rules as the animal kingdom - that bigger animals live longer, and smaller ones die quicker - in a predictable proportion between size and longevity. Think fruit flies and whales, duckweed and Sequoia. I know that this fact have been known long since long ago, and its no news at all but its a good time to reflect why this is so. Humans only have about a hundred years to savor life on this planet. Our natural lifespan follow the same ratio described above.
Is there a way to live forever? Proponents of longevity struggle to break the barrier, and I do believe that in the future, the lifespan of humanity will be extended a hundredfold. But still mortality will remain forever. As stated by the second law of thermodynamics, our bodies continue to decay into entropy.
The only way I see to transcend mortality is to live life to the fullest by living according to your purpose, here and now.
