Yes, thanks for posting this info. I referred to this when a 3rd grader asked what happens to the body to make it faint, as a girl in glee club had fainted onstage earlier in the day. The kids also wear a similar harness at our local YMCA to do their rock climbing stuff so it also became more interesting to them.
I was thinking that there must be an effort somewhere to design a safer mechanism to prevent falls without endangering blood flow, don't you think?
The full body harnesses used in rock climbing may also cause that problem.
However, the normal, or sit harnesses used by climbers that already have developed hips will not cause fainting or death nearly as easily. When coupled with a chest harness, they can be very comfortable, but will not be up to safety codes for workers.
