I do know what you mean. I grew up in northern Canada where seeing -40 was an annual occurrence. But when I've traveled to warmer places I've often found that I can be colder indoors than I ever would be at home. When it's the difference between life and death then buildings have central heating. But if it's a matter of comfort, central heating seems to be relatively rare. Even in the wealthiest countries.
