I have a strong dislike for overused words and phrases such as "inspirational" and "it changed my life," but this vid truly is inspirational and may just change your life. Be prepared to cry a little. I can't embed, but here's the link. You may have already seen it (especially those in Britain), but the rest of you: watch.
WARNING: The YouTube video plays upon opening. Yes, I know I said I hate these things. But this one is worth it.
