Response:

If we are spiritual beings merely using a physical body, then the end you speak of, namely physical death, is not an end to one’s spiritual existence and journey at all. It is the choices we make toward self-awareness while in a physical body that matter toward our spiritual awakening, not whether our body is immortal.  That is the reason why we should make healthy life choices.

But even if you believe you are nothing more than your body, and physical death is the end of your existence, then it only makes sense to take care of your body to extend your life and improve the quality of it.  In neglecting your health you will be throwing away your experience of life.

Love,
