Infinitaneous 

The certain ability of a thing or an entity to stay infinite throughout its life-time, until it chooses to destruct or die, willingly or unwillingly due to certain instictintive or natural conditions.

Turritopsis dohrnii, also known as the "immortal jellyfish", can actually 'Reverse' the process of ageing, and thus, the name. It is until, its eaten by bigger predators of the sea or it catches a disease in the Medusa stage of its "Age Reversal"

The life of Lord Rama was infinitaneous, until he chose to willingly die.

infintaeneous 

infintaeneous describes a moment which started at the start of time and goes on until the end of time. The only true infintaeneous moment is one which started at the beginning of time. so we can't have an infintaeneous moment start now. It's often used as a metaphor. The antonym of infintaeneous is instantaeneous

Grrr it's taking an infintaeneous moment for the bus to arrive
