Besides the lack of heat, this time of year, there are lots of folks that would find 59-60* warm. They'd be outside in shorts and t-shirts, but that's likely because they are used to it. The human body can get used to certain temps, and if you then put the body in an environment that's far enough outside of those temps, the body will feel hot/cold.

For instance, I read an article this past year about a major health risk during a marathon in England because the temps were going to be 80 or 85*. For us here in Houston, that would feel great in July/Aug. Everyone would be outside enjoying the "cool" weather.

When I lived in Japan, during the winter you'd occasionally have a day where the temp got up to 35-40 despite there being 2-3' of snow on the ground. You could comfortable go outside in shorts and a t-shirt because you were used to temps <32.

13 below this morning........had to put on a jacket.

Someday we will return to traditional building methods, provided the times allow:
Log or stone block walls with overbuilt integrity.
Slate or tile roofs.
More permanent materials used and/or better designs to let nature do the work.
Central heat source and cooking combined.
Versatile venting systems depending on the season.

There is comfortable free heat (or cooling) always just below us. All year round.

Wind chill!

My daughter went to college in Fairbanks.
There is a sign at the campus entrance with a reader board showing the current temp.

A common thing students like is to get a picture in front of the sign wearing only a swim suit at -40.
Of course, their car has the heater going full blast, and they are outside only long enough to get the picture and jump back in the car.

Fairbanks usually has very little wind. Dead calm is normal.

During freshman year, my wife was worried our daughter wasn't dressing warm enough.
My response- She's only outside for two minutes at a time between classes, dorm, cafeteria, yada yada...

One evening after class she had to push hard against the door against the wind. Took one step outside, and quickly got back inside.

That is one 'cool' pic!
I wouldn't be that brave..at that temp.

UAF has a few of these around campus during the school year.
They are the UAF "Nanooks", the native word for polar bear.

With no wind, the sun out yea, 40 degrees is not bad. Try sitting inside, in a t-shirt, and shorts, no blankets, in 58 degrees. It is dang cold without the sun shining on you.

At the hotel in Boca Raton last summer the hotel room was 66 degrees. When walking back for the 3/4 mile hike from the parking garage, we would be hot and sweaty. The 66 degrees felt glorious. It required a blanket at night but it was great having my brother there enjoying the temps. We both knew if our wives had been there they would want the temps set at 74 at the minimum.

Yesterday and today (24th) just like spring.....
 

I doubt it will last but I'm sure going to enjoy it while it's herehttp://forums.pelicanparts.com/uploa...1579886235.jpg

When I was in college in Tampa, I had the thermostat for my end of the dorm in my room. The problem was that the only control that it had was the temp, nothing for fan or AC/Heat. So it'd be in the 70s with the AC running, then a cold front would come in and drop the temps into the 40s or 50s. I would turn the thermostat as far as it would go, but since the fan was set to "on" and the HVAC was still set to AC, our rooms would drop to 60*. That was damn cold to us. That was the only time in my life that I remember sleeping with my head under the covers. Even when I was camping in the Boy Scouts in Japan and had to clear the snow from the ground to put the tent up, I never slept with my head under the covers. Of course, I was used to the cold then.
