An Austrian radiologist, Hermann Moedder, experimented with medical students in the 40's, hanging them by their wrists with their hands directly above their heads (much like the Watchtower pictures Jesus on a stake). In a few minutes, the students became pale, their lung capacity dropped from 5.2 to 1.5 liters, blood pressure decreased and the pulse rate increased. Moedder concluded that inability to breathe would occur in about six minutes if they were not allowed to stand and rest.
The same would apply to Christ, IF he were suspended on a stake as the Watchtower depicts him, hung from hands bound directly overhead, he would have suffocated in a matter of minutes.
Terry, I often thought that this WT depiction of Jesus was physically impossible:
There is an photographic image that exists that depicts individuals strung up on posts. It is a staged photograph illustrating the punishment posts that are alleged to have been used by the SS during WW2 in Germany. The photograph was taken in 1958 but it shows how a person would look if they were hung on a stake.
