Interesting question: how come tattoos don't disappear after 12 years?

The cells remember the ink, basically.

Rubbish. It's the epidermis that is shed throughout your life. The
epidermis is the top layer of skin. The reason tattoos don't disappear is
that the ink is injected below the epidermis, into the dermis. That's a
deeper layer whose cells are far more stable.



Yes, it's true the epidermis sheds but we're talking about your cells
regenerating which is a different thing. Your whole body has different
cells than it did 7 (some say 12) years ago. Every 7 (or 12) years you're
a new you.

Please follow the thread, not just read the last bit of it.

I'm following the thread quite adequately. I think you're getting confused.
You stated that "The cells remember the ink, basically." I'm saying that
they don't. The tattoo doesn't fade because the ink itself doesn't move.
