Bearings That Budge

When I first heard the name of bearings, my initial thoughts were about someone’s location. Like in shipping or military. To my surprise I came to know that bearings surround us all, wherever we are. Not just now, but for thousands of years already. No matter we are in our car or kitchen, they’re there. And don’t think you can escape them. They could be in your watch or smart phone, or even closer: in your mouth when you visit your dentist.
