My first thought was that maybe people at higher latitudes are less active, as they are remaining indoors to keep warm. On the other hand, when it’s very hot, people are lethargic.
My second thought was maybe it’s an evolutionary adaptation: people at higher latitudes have more fat to keep warm.

Behold, this was the iniquity of thy sister Sodom, pride, fulness of bread, and abundance of idleness was in her and in her daughters, neither did she strengthen the hand of the poor and needy. And they were haughty, and committed abomination before me: therefore I took them away as I saw good. (Ezekiel 16:49-50)
While increasing in material goods, America has weakened the hand of the poor and needy as regards spiritual and family values, thus having a negative balance sheet.
