If they want to. There's no obligation to stop but none to continue either. Honestly though...even if you retire and decide not to work any more. You're still going to do it. Cause...you love it. No-one has the right to tell someone to stop doing something they love.

If they feel like their artistic journey is over then absolutely they should consider it. If they feel like they want to continue for a longer time, then they should continue. It's not like we should force all artists one way or another.

you are never too old for art!
i mean, i believe it's ok to retire from making them for the purpose of selling
but a person who enjoys art should make some pieces after their retirement, just for fun or something

i think there is no limits and age for art....

Commercially, I can see it.
But personally, for your own pleasure, I don't think it would be possible to stop.
I can understand taking breaks every now in then, sometimes life is hectic and sometimes we are just not in the mood.

It's like the saying "You can take the frog out of the pond but you can't take the pond out of the frog."
I think being an artist is something that is lifelong.

Art is not a job, it's a way of life.

because an artist will always feel compelled to do art when he's inspired because i don't think of it as a job its a passion.

I don't think its possible to stop creating works of art, even long after going into retirement.

as a profession you can't really retire... um i don't know how to explain

i cannot speak for other people but from my own experience art is not something you retire from. not that i'm old enough to say so for sure art is a compulsion, an expression of self and i don't think anyone "retires" from that. there is no age limit or desire for your own expression of self^.^
