Qi Gong Demonstration - The Use of Chi

I found this video the other week...the video is a documentari and its sorta long, so just bare with it.
There's so much to know about this subject, just google it and some research on your own time.
Qigong is the Mandarin Chinese term used to describe various Chinese systems of physical and mental training for health, martial arts, and self-enlightenment.(found this on Wiki)I was so amazed by this video, because I don't know anyone or seen have seen anybody who can produce heat or sort of energy using "Chi". I guess that's what this video is reffering to. The Person on the video doing the Demonstrations is John Chang, Im not even sure if that is his real name, because as it was mentioned in the video, he didn't want his name to be put out there in the media.

Concrete Breaking World Record

I was at the gym the other day watching this clip, on "Sports Nation" I think...as one of top 5 weird Breaking News or something.
My reaction was like, How come its Weird?...lol..well sorta
I thought it is so much time and unimaginable dedication to accomplish such thing.
Last time I saw concrete breaking was nothing like this, maybe just four pieces of concrete blocks or a little bit more. And now I see a video of a guy breaking 700 concrete blocks like nothin passin by the street.
I wonder how the process of conditioning to overcome something like this.
His Name is Narve Laeret(never heard of him before), And he just set the world record for concrete breaking.
His like a killing machine with those punches.
This makes me think that Humans are capable of anything since we upgrade and improve everyday. Probably in the future some people will have those special Human powers from deep conditioning and concentration.
