You can often think of techniques as being tools in a tool box. Each one has a specific role, and each occasionally needs to be picked up, used and then placed neatly back in that toolbox. Some tools, the ones used often are near the top, others rarely used have to be rooted out from the bottom, gathering dust and grime. An unused tool soon rusts, and becomes alien in the hands of the user, the once fluid dexterous motions forgotten.

I felt like it was time to get some old tools out and see what was what.
