If you're talking up to a couple thousands years ago (Medieval up to Roman times), it was possible to live pretty long if you were wealthy enough to afford food and shelter. For reference many well known greek writers reached 70+. If you're talking prehistoric times, the food supply was very limited with no agriculture and no trade. You'd die of food shortage sooner rather than later, physically unable to hunt or to keep up with the nomadic tribe. That is assuming that one didn't die because of war or disease. Most infections meant certain death with no antibiotics.
