Are you working in the buff?

Don't know any reason why cold temps would bother a PM. You'll be wearing protective clothing I would assume. Have had no problem skiing in subzero temps.

Superconductivity?
Once upon a time, back when I was Pop's age, I understood it - slightly. This was in about 1963 shortly after physicists had first started to come up w/ an explanation of how it could be created & an understanding of what it was. That was also the time when lasers were first being made that could do something besides make people say "Gee Whiz!"
Super conduction was a state reached just above Zero degrees absolute - somewhere around -273 degrees below zero Fahrenheit. Electrical resistance dropped suddenly to Zero & electric currents, once started, could flow essentially forever w/o decaying.
About the only super conducting materials in 1963 were a few metals, but some other solids were capable of the phenomenom. All a pure research stuff on a small scale. Between then & when I retired in 1987, they had developed BIG stuff that depended on super conductivity. Specifically, BIG electromagnets to operate a project in Texas south of Dallas called the Super Conducting Super Collider. By then I had forgotten all I ever knew. The SCSC was a buried circular tunnel about 54 miles in circumference & well over 100 ft below the surface.
Cost killed it after about half the tunnel was bored & the Huge magnets were being fabricated. Our #1 Daughter's Father-in-Law was the construction project manager when it was killed by Congress.
He didn't know beans about superconductivity - he was a civil engineer, but he knew project management. The cost of that project almost dwarfed NASA - that's why it got killed - did not have enough political support for its size.
There are superconducting electromagnets in MRI machines, also. It was amazing how fast the technology developed once the basic phenomena was understood & materials found thet exhibited it.

We are very lucky to have these devices.
Good Answer, Creaky...

...You stole my thunder 'cept I was going to use the old Lewis Grizzard term "Neked"!
Although if you plan on taking your pet snake w/ you, it would have one heck of a time moving at those temps.
