Imagine you are living 20,000 years ago. You huddle in a dark cave, shivering under reindeer or bison skins. As you peek out at the ice, you worry that a cave lion or cave bear may try to share the cave with you.
Your teeth are chattering, and your stomach is growling. You keep wondering when the hunters will come back with meat. The fire burns day and night. It’s the only heat you have. That’s how life was. It was way harder than your life is today. Good thing you can stay safe and warm as you explore the Ice Age from the twenty-first century. No need to bundle up.
