Working in an igloo is a joy. An igloo is a very cold place that sometimes can resemble an office. People who work in an igloo have more chances to avoid aging than those who work in a warm and cozy place.
One advantage could be the following: Imagine yourself having a very hot cup of tea that you want to drink right away. It is so hot that you have to wait a while. Your nose is already cold enough because of the low temperature, so you may introduce it into your cup of tea, using it as an ice cube, and cool it down in a minute. Overnourished people are usually glad and happy. They can have fun looking at the undernourished ones, shivering, struggling, quivering covered by blankets, gloves, hats and a little device especially designed for the nose.
On the other hand, the poor tiny creatures can not stand the inclement weather. Their hands are frozen, they can barely type, move or think, turning into miserable living things.
I think the future man will find the best frozen specimens for their experiments in these igloos, and they will write in their books something like this:
“In the year of 1994, the prehistoric men was kind of masochistic. They used to like working in very cold environments, so cold that on an unexpected day, all of them died of hypothermia. The men of the past did not know how to regulate temperatures. What was the thermostat created for?”
