life, death, and age
well first of all aging is just something that happens over time, to grow old and so wither. is a part of life however what you asking is should we cure aging, not death,
if we could stay young even in our dying moments I think that would be interesting. for you could still follow things you want to do even in old age. my guess though is to show age parts of you would still age, your hairline may still recede. and you can have all the freedoms of youth but when you are ready still go. everyone thinks aging defines death and life but it doesn't die is a constant in life. life is something that lives a cycle. aging is just age, take a tree for example starts as a sapling then a small plant, and up to a huge tree that then rots. that's life.
but if we can stay young till death then won't that be interesting?
but in the term of your question: should death be accepted, or should we strive to preserve life?
there's only so much you can do. death is still there it always will be aging is just a look it doesn't change who you are, it just changes how you look. you can preserve life forever. death will always check up its the way they are. they go hand in hand.
