Old school, new thoughts

Thanks Dr Karl, Lucy and everyone else who contributes. I love listening and learning new things every week, as well as validating some old school learnings! I appreciate the work you guys do to help us keep an open mind, and encourage the continued quest for knowledge and to maybe, just maybe, use that knowledge to do good!
