Not sure about the lifespan, have never seen aged tattoos from that guy.
I think it will hold up rather well, because the shading is done via a lot of single dots,
but I really am no expert on the matter.
I think you could 'sharpen up' something like a tribal tattoo that has blurred (by re-doing it, basically),
but I'm pretty sure there is no way to 'sharpen' something like the above.
