In a previous life, I’m pretty sure I perfected the art of bartering. It doesn’t fail me, even in the 21st century. I’m not great at the 21st century. Bartering is the ideal system for me. Based on a very important and flexible system, where value doesn’t involve exchange of money, it seems more equal. I’m naive about exchange of goods for money, though I recognise it has made the world ‘spin around’ for centuries.
