I think I first started to realize I was getting old when I could no longer watch videos like this anymore. I have personally known too many people that have sustained serious life changing head injuries because of accidents such as the kind featured here. Anyway, sorry to get heavy. 5 stars.
This video makes me feel old for another reason. I've always enjoyed watching people hurt themselves for free. I'm angry that obamacare is going to force me to pay for this pleasure. I feel like a 40 year old republican.
