That is completely true. A continuing education course will also energize the mind. However to avoid burning out quickly it pays to take it step by step as it comes. In every lesson as a facilitator, throwing questions back to class for their contributions will make them more active and save the instructor a few calories. A good number of students will take up the challenge and answer. Others will research if asked to do so and bring answers later, they will happily do so. It delays burning out.
