This video is very sad and should be watched by adults and mature teens. It is a very special and worthwhile video about a wonderful young man (Zach Sobiech), who found out he had a rare form of terminal cancer at the age of 14. His goal in life was to make people happy, and people loved and admired him for that. Sadly, passed away on May 20, 2013. A research fund which has been started to help change the fate for other children like Zach has been set up and you can donate to the research fund set up on his behalf. You can also buy his album on iTunes here, with the proceeds going to the research fund.
