I don’t think there’s any way to do a non biased study.
Having said that — there sure are a ton of anecdotal evidence
My FIL was dying in hospice and held on until his wife and daughter told him they were going to be okay.
Keith Olberman tells the story of how he was reading a story to his dad, and he says as soon as he finished the story his dad took one last breath and passed.
I truly hope Mr Carter could remain with us for about another month and a half.
Nice. 👍
