During several days of testing at the Mayo Clinic last week, Glenn witnessed a privatized hospital treat people in remarkable fashion during what he called the "best hospital experience I've ever had in my life."
So why was Glenn at the hospital in the first place?
"I had lost my voice over the summer, and I just wanted to make sure that was right," Glenn told radio listeners Monday. "And some things that have been happening in my life over the last five years have returned, and I've been struggling with some things again."
Long story short, doctors found the answers they were looking for.
"It was very good for me personally," Glenn said.
He then explained the incredible, groundbreaking work he saw carried out by doctors and scientists at the facility, which Glenn attributed to capitalism at its finest.
"We have, through capitalism, the opportunity here to seize a point in history and to make sure that it is not harmed. We are at a point to where things will grow that are beyond our understanding," Glenn said. "We are on the edge of the Renaissance."
