Trade has played a vital role in the social evolution of humankind. It allowed people to specialise, which raises both skill levels and efficiency. It brought people from different lands together, co-operating rather than competing over resources.

Metaphorical tone deafness is when people are unable to discern what is of value in something. I think I'm tone deaf to poetry, for instance. Despite having studied it into a second year of university, most of it just leaves me cold.

From time to time, I'll look back through the personal journals I've scribbled in throughout my life, the keepers of my raw thoughts and emotions. The words poured forth after my dad died, when I went through a divorce, and after I was diagnosed with breast cancer. There are so many what-ifs scribbled on those pages.

My grandma actually put me in girdles when I was around nine or ten because I had hips even then, and she didn't want boys to be attracted to me. Having hips meant you were a full-grown woman, and I was too young for that.
