He was never embalmed
I'm sorry.. the Detective in me (I really was) can't help but notice your statement "He was never embalmed"
contradicts with your later explanation when made aware of the embalming technique which would include a really unusual step of filling the coffin with nitrogen;
"Not really blah blah his body was injected with formalin"
Formalin is also known as formaldehyde.
"This is certainly one of the first methods that will come to mind when thinking of ways that bodies are preserved. The use of formaldehyde has been the predominant method of embalming bodies since this chemical compound was discovered by German chemist August Wilhelm von Hofmann in the 1860s. Not too much has changed in the world of embalming, with formaldehyde sitting as the foundation."
So here is a classic, classic opportunity for Coach to say "I was wrong" opposed to what is likely to happen, a continued denial of facts. So what is it going to be Coach? I hope I am plesantly surprised, but given your track record with the election results, I'm not holding my breath
