I’ve heard a lot of talk recently about how we’re the only species who don’t hibernate. (Which I have looked into and found to be false. Fish are also incapable of self-induced torpor. Must be all the water). But I think the point they’re trying to make is that we should be winding down when winter comes. That our bodies aren’t biologically programmed to work a 9-5 schedule year round. (But really, who works a 9-5 anymore? That’s a utopian myth because it’s likely been pushed out to a 9-6 now, which is essentially a 7-8 when you factor in commuting and all of the things that you have to do around work which feed into the next day).
