    Some could be nearly as old as the universe [~14 billion years]. Supermassive pop III stars could go nova in less than 100 million years. Some of their offspring could also have expired after a similarly brief existence [although not quite as quick as their metal free parents]. But low mass grandkids of the first generation could still be around - hence nearly as old as the universe.
