GoPro makes affordable, hi-definition cameras that you can attach to yourself while you do things.
It’s used in a lot of sporting events, to show a first-person point of view when an athlete is, for example, skiing or doing motorcross or other high-speed, high-intensity things, as the perspective is quite thrilling to those who have no shot in Hell at performing such a task.
They are cool. Some are mesmerizing.
Few are as heartwrenchingly sappy and tear-inducing as this.
(Obviously, watch in HD for maximum tugging of your heartstrings)
