Damn
I like deadlifting and the benefits are obvious, but this type of thing always keeps me weary from making them a part of my routine. No matter how good your form is, the human body just flat out is not designed to lift weights that heavy. It was obviously a freak accident and shouldn't deter people from doing deadlifts, but what about this logic:
I'm not a powerlifter, so if I can't reach my fitness goals without having to possess a 400 lb+ deadlift, then perhaps I need to rethink my goals

Thats just my point of view. Other people really like to push crazy heavy weight, thats their choice as adults.
There is a reason that I have vowed never to add a single pound to the barbell once I can squat 225 for 5X5 though. There is nothing in my life that I want to accomplish that a 225 squat for 25 reps in 15 minutes won't get me to. I'm not gonna compress/stress my lower back any more than is necessary.
