[Pseudoscience-is-malarkey (OP)]

I did some research on this photo of my grandfather (right) and it appears to have been taken at Bristol, England's now-defunct Frenchay Hospital during the war. He's wearing an MP badge and helmet but was not actually one. He's most likely just goofing off in this photo. He was actually being treated there for a spinal injury from a mine explosion three months after landing at Utah Beach. As if a painful spinal injury isn't bad enough, it metastasized into Pott disease (proof of mother nature's cruelty). After surviving the North African campaign without so much as a scratch, he might have thought he was invincible. Although he looks healthy, happy, whole, and vital in this photo, he would soon deteriorate further and further into his sickness, eventually dying in 1950, a few weeks before his 30th birthday.
Anywho, anyone familiar with it?

Frenchay's other claim to fame was the site of early clinical trials of Viagra.

Bristol, England's now-defunct Frenchay Hospital

It doesn't seem to be very defunct.

It's a lot smaller than it was -  not much more than an outpatient rehab unit (and a huge housing estate, of course, like Filton airport).
