Being Immortal means living for ever.
The question is how can I live forever in physical form?
The answer is by choosing many different life-times.
Why would I choose just one physical life-time that lasts forever when I can choose many different possible life-times as my space-time-reality?
The physical body is not designed to last forever.
Forever means eternally or everlasting time.
Eternity is beyond the limited realities of space-time.
My Soul is eternal.
My Soul is immortal.
My Soul never dies.
As my Self, I am mortal.
As my Soul, I am immortal.
I choose both on my journey of life & death.
