Assuming convection only, and sufficient ventilation....warmer upstairs.
Personally... downstairs 'cause I wear long-johns and flannel lined jeans! The house... it's upstairs in our kids rooms - the heat from the wood stove rises, and it's like Summer up there!
Thats down matey ive only an oil lamp up there and its cool off period time.
Heat rises and my townhome face the sunrise in the morning/noon/ so it's warmer upstairs than downstairs all year round.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
