As an aficionado of industrial design, I find the G-tube admirable. A small tunnel is opened above the belly button and leads directly into the stomach. Food passes through the tube. I dine. No fuss, no muss.
In earlier years I would have found this idea horrifying. Not so much now that I need it to stay alive. Invention is the child of necessity. In this invention, common sense was more important than genius. The Egyptians first hit upon the notion of tubes for feeding people centuries ago.
I learn on this site "the ancient Egyptians used reeds and animal bladders to supply patients with a mix of wine, chicken broth and raw eggs." Indeed, "after President James Garfield was shot in 1881, he stayed alive for 79 days on a mix of beef broth and whiskey."
