Eli5: Why is it so hard to sit still while talking on the phone ? Why do people always get up and pace around while on the phone ?

It's all about using different parts of your brain at once.

People are saying it's so you can get other jobs done at work, or seem authoritative, but that doesn't exactly explain why we do that in our own homes during personal calls.

Think of talking to friends, it's often to easier to do when you're also enjoying a meal, walking, playing games. etc.

I've even heard of people who play Mario Kart while on the phone, deliberately, during professional calls, and who say that makes it easier to focus.
