I remember a site that showed that if Jesus was hung the way jw's claim He would have died within 10 minutes or so. Showed my jw some of the articles, obviously made no difference.
Here is one article-
https://www.theguardian.com/science/2004/apr/08/thisweekssciencequestions
"....One of the most severe methods of crucifixion put the arms straight above the victim. "That can [kill in] 10 minutes to half an hour - it's just impossible to breathe under those conditions," Ward says."
