<p>Dan:</p> <p>I have to agree. This can be a challenge when attempting to draw analogies and reference "real-life" experiences. I find that sculpting these aspects of my lecture to meet the greatest percentage of my target audience is essential. The closer you get to applied knowledge, the more likely you will retain interest in the subject matter.</p> <p>&nbsp;</p> <p>Thanks!</p> <p>&nbsp;</p> <p>Richard--</p>
