About 2.5 million years ago, humans chiseled stone tools and hunted the likes of mammoths, bison and deer. They foraged for berries and consumed plants, roots and grasses that most modern humans have no idea you can eat. As they laid to rest in their bare-bones huts, they probably felt pretty fearful, with reason—you never knew when a saber-toothed tiger or a deadly snake might strike. It perhaps comes as no surprise then that humans lived, on average, to reach just age 25 during this era. 

While historians don't know exactly what went on back then, experts have attempted to emulate prehistoric conditions as closely as possible. In fact, about five years ago, a reality TV show called "10,000 BC" sent 20 British people to a remote area of Bulgaria, tasked with depicting what it would have taken to survive in the Stone Age. Modeled after the Mesolithic time period, the people received only some flint, scarce food rations and a couple of basic tools. While they definitely struggled and despaired with consuming insects, gutting boars and generally "making it" in the Stone Age, they still possessed the support, comfort and safety that our ancestors definitely lacked. 

So, if you traveled back to the real  Stone Age, full of fearsome beasts, poisonous plants and natural disasters, how long would you last? When you take the following quiz, you can find out just how you'd stack up against your bigger, burlier ancestors.
