Like the relations of many others, to refute aging does not stop death. We must also consider whether it is aging of the appearance of beauty, aging of the physical body or aging as in never dying.
If we were to combat the aging of appearance, the body will still deteriorate physically and mentally, leading to death. If it were aging of the physical body, your mind will still be reduced to that of a child as you continue to age. If it is about living forever, I can ascertain that you do not want certain people in high places to live forever.
Why live forever though? The earth is already in peril, but, knowing humans, we would most likely take this eternity for granted and destroy the earth even more so. There will be no future generations to overcome the challenges and, knowing that their lives will not end, the producers of the earth's assassinators would not stop but only be more engaged in fads and trends and become wastrels.
