Mathieu, This is excellent! I appreciate how your idea can potentially impact more than a single group in a positive way. The older adults would receive the knowledge they seek to acquire; teenagers and younger adults would receive volunteer hours, something to add to their resume, or even a stipend; schools would receive beneficial exposure; the possibilities are infinite. Even with the possibility of schools not agreeing with the usage of their classrooms during the summer, this is a solid idea, and I can't imagine other areas, like community centers or places with a "school feel", not agreeing to this.
Darren, I personally find this interesting. I like your new perspective of how these kind of commercials empower seniors. Pepsi Max made commercials with the exact same concept as your soccer video, except they utilized the sport of basketball with current NBA superstars. You should check out their videos. I think you would enjoy them.

Rami, The articles you provided contain excellent insight on the topic of reverse mentoring. The clear acknowledgment of potential problems along with the first-hand experiences paints a clear picture on how young people can truly assist in an older adult's life; including, in the working enviorment. From reading, it is quite clear that the foundation of reverse mentoring is trust.
