His arms were stretched at least six inches longer than his normal span, which means all of his bones from wrist to wrist were pulled out of their sockets.
When he tried to take a breath he would have to stand up as straight as he could on the one nail that held both ankles.
The reason why he died so relatively quickly was because it was a tremendous effort to raise himself up in order to take one breath - this caused tremendous strain on his heart.
Experts have surmised that Jesus died of cardiac arrest - a broken heart.
John 15
9 As the Father hath loved me, so have I loved you: continue ye in my love.
10 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
11 These things have I spoken unto you, that my joy might remain in you, and that your joy might be full.
12 This is my commandment, That ye love one another, as I have loved you.
13 Greater love hath no man than this, that a man lay down his life for his friends.
14 Ye are my friends, if ye do whatsoever I command you.
It's one of those things about life having purpose and meaning, animation of soul and spirit - that to love and be loved is life back from the dead.
