Scientists have finally discovered why we swing our arms when we walk. The scientists involved in discovering why were called David Lloyd and a man known as Collins. To start off with they made robots that swing thier arms and also some that don't to see what would happen. They set the robots off and the ones that didn't swing thier arms started to sort of spin around rather than walk in a straight line. The two were astounded by what the robots did and they decided to test on humans. They got a few volunteers and got them each to do different things with thier arms. They made one person walk normally, one person keep thier arms still and one to swing thier arms with the wrong legs. They found out that the one that did not swing thier arms and the one that swung with the wrong legs felt like they had a 10kg backpack on thier back because it took a lot more effort to walk whereas the one that swung normally took very little effort to walk at all. It turns out our body makes our arms swing because it takes the least effort and it puts no stress on your muscles.

This is the robot that they used to test.
