@oralloy,
First, I didn't advertise any product nor were there were links in my post. So your first paragraph does not apply. This is a theoretical discussion that applies to any living being.
I remember in HS asking the theoretical question: If you were condemned to death for some crime but given the opportunity to choose your method of execution, how would you want to do it. Most people's jaw dropped because they could or would not fathom the thought. They were "in the box" thinkers. I am not.
So the question is being re-presented 38 years later and I propose a hypobaric chamber or slow freezing with appropriate pain meds to give it a smooth ride. Don't
read between the lines. There is nothing there.
This is a purely practical theoretical question. No moral or legal issues to be injected.
