Well, with someone who was in England, Ireland, Japan, France, other European countries, and who knows what Muslim countries..., one would have no idea...
And who knows what the requirements and/or laws are in those various countries...
My inquiry isn’t related to laws as much as the actual performance of the procedure. With Jackson’s nasal passages compromised due to extensive surgeries, nasogastric route would likely be quite difficult, and in a home setting no less. Color me a teensy bit skeptical. It rates up there with performing CPR in a bed.
