No because all life ages yet cannot be said to be living "unhealthy"
lifestyles. This is true of "immortal" cells like bacteria too: if you
prevent them from dividing, but do not prevent life, the will die after a
time (they senesce and ultimately fail).
Groupers and other sea life, as far as we know, have an indefinite
lifespan, barring accident or predation, yet it requires constant
growth. Yet you do not find such creatures beyond a certain average size
so death claims ALL of them eventually...and before they grow to any
especially monstrous size. In any case, this method is not open to us.

Theoretically, there is nothing impossible about regenerating a limb or
even an organ...such is among the possibilities from future biotechnology.
Yet even these creatures age and die. Where are the immortal salamanders

Impossible in principle. Sunlight, oxygen, the very products of normal
metabolism, natural chemicals within plants we eat (oh yes, the benign
vegetarian diet contains many natural insecticides and other toxins which
can lead to cancer...the plants didn't evolve simply to be foodstuff for
everything else. They have and need defenses to improve survival too and
they are not all harmless to the creatures that consume them). So...how
do you eliminate "carcinogens and other environmental toxins" without
eliminating everything in existence?
Life requires death for meaning - for its very definition. No death,
