You need to understand:-
"In the above form/sense we are immortal, otherwise not/can't. However, we can think of just "Longevity" in our present form.
Can we say that " Longevity" or " great regeneration capabilities" is/can be just effected by the environmental effects surrounding us?"
Means, we can't be immortal in our present human body form. Longevity of our present human body form can possibily be improved by improving environment--which may ultimetely leads to improving the body environment & so the life span. Opposite can effect just opposite.
