This is a short video of 39-year old Mark Tamlin telling the story of how he fell off his son's hoverboard and got a concussion and suffered from amnesia for a couple days and thought it was 2010. He's all good now, although he still doesn't remember the day of the accident. See, this is exactly why people shouldn't ride hoverboards. 2010 sucked.
Keep going for a video of Mark telling his not so fascinating story.
