Nice clip boozich, thanks for this.

Sometimes an idiom seems like a cliche, where there is a vague meaning. When their history is seen, they are often easier to understand, and any doubt about their meaning can be put into context. It's always better to know what we mean when we use them, and have a better idea of what others are likely to think they mean. Knowing their history can color in some of the blank spaces.
