It's weird- no matter how times I do it. But I don't know of literally anything else on earth as exhausting as shoveling. I've experienced it before and I think I was just as surprised by it. But in just a few short hours I am experiencing a level of wiped that can only otherwise be achieved by not sleeping for let's say... three consecutive days.
It's not just the physical exhaustion- although that's definitely remarkable. The ache in muscles you don't normally use and in every single fiber of your being. But the real head turner is the mental uselessness. Like anything beyond starting out like a zombie takes more mental faculties than you currently posses. It's such an odd sensation.
I'm not complaining, just marveling at the phenomenon.
