As an introductory thought to this blog I thought I’d talk about metaphors.They rule our everyday life and we never really give much thought to their use. Which is why I feel so bad for roller coaster designers. (bear with me, this has a point). They have so much riding on them, (literally). Metaphors like ‘life is a roller coaster’ would mean nothing if people with such imagination didn’t keep striving to create the highest, longest, fastest, scariest, BEST rides imaginable. I owe roller coaster designers so much. Most people would have nothing to compare their lives/strives/problems/emotions to. They deserve our respect. Nowadays, we expect the rides to live up to the expectation that they will be as vicious and frightening as our lives are. What a job.
