You have given me much to think about...

Change and age are ways of interpreting the evolving environment around us (and establishing our position in that environment), and the constant miswriting of DNA that leads to what we call age. It all goes away when the body dies.

consider also that, for instance, your hand, will be completely replaced over the years - cells will die and be replaced completely. So how are you still you?

i think it's because age is an illusion, we are made of fourth generation star stuff, indestructable, seemless, endless

I think the reason that this part of us does not seem to age, is we cannot observe with the five senses that most humans use for observation. though we are constantly changing.
