Most "lifelong learning" programs seem cobbled together, a way of occupying professors' free time while providing a little extra "enrichment" to their institution. But the University of Denver's popular and varied offerings range from art- and music-appreciation courses to writing workshops and cooking classes, culture-soaked trips abroad, lectures on current events and more. The instructors include some faculty but also quite a few professionals in various fields, immersed in the topics they're presenting. Think of these sessions as booster shots for the mind and spirit, without the tedium and hefty tuition bills of full-time higher education.
