I think he'll atleast go on until he's 50. Thats a nice memorable number and he's pretty close to it now. Having a title or fighting for one in your 50s is probably an appealing fact for Hopkins. If he's still beating top guys at 50 I think he will go until he's beaten badly or ko'ed. He loves to box, he's still good at what he does, he loves the attention, he makes good money, and he's a ratings draw. I don't think Hopkins is going anywhere quite yet.
