Save this one somewhere for future reference.  All around you (and in your own family if you're really lucky) you'll find elderly ladies and gentlemen with a world of experience etched on their faces and on their souls. Often we're too busy rushing around to sit and listen, but with experience comes wisdom that can't be bought. In this truly lovely video, presenter Riyadh Khalaf approached some such men and women and asked them to share one golden piece of life advice, as if they were talking directly to their 16-year-old selves. The result is heart-warming and life-affirming. http://www.youtube.com/watch?v=Qo0Q975u_WQ
