@DeanTTraining I can see why assisted pull ups can be harder than non assisted, because it forces the torso upright so less back muscles can engage like in a horizontal pull. This would make it amazing for those muscles it stretches deeper
Ive never heard of them having relatively high rates in it, it would be a surprise considering their obesity rates are nothing like the rest of the world's. If their rates of cardiovascular disease are relatively high then i think the simplest explanation would be that they are more health conscious and actively get more check ups and tests done than elsewhere
It really depends on what you mean by feeling cold. Like you can feel the cold around you, maybe even short periods where you feel it bite, but your own body temp is still high. As soon as your body temp falls, it is stressful and hypothyroid, especially in feet hands and face.
Paleoithic and bronze age nordics relied on dried berries, grains, honey and milk as winter staples
The cold signal is there, the importance is that you don't feel cold despite it: that is what it means to have cold thermogenesis.
The fat oxidation also needs to be supported proportionately by glucose metabolism, or stress hormones will rise from lipolysis and thermogenesis falls and focuses on the vital organs, with fat being preserved to insulate not to create heat. Protein catabolism then becomes the stressed body's preferred heat fuel.
Basically you can get away with burning more fat in winter because you can increase carb intake to become hyperthyroid
