Some people recognize that heating & cooling is luxury, but I have discovered & really recognize that heating & cooling is no longer a luxury, especially in this country, but every year you can hear about people who died of heatstroke in the summer time because they did not have good air conditioning or they chose not to use it because they did not assume they could afford it. The same holds true in the winter. Especially this winter, the headlines are full of people who are entirely cold to death, either because they do not have any Access to heating or they are not using it for 1 reason or the other. There have been lots of Winter time storms, & that means that there has been lots of power knocked out, which also means there are people without heaters. Even when the weather is not as cold as it has been, heating is vital to life. Whenever the caveman or whoever discovered fire, they did a good thing for Humanity. In addition, the nurse who discovered cooling for the hospital where his TB patients were suffering, also did Humanity a big favor. We care about to think that we can do just good without Heating & Cooling, & in fact it is true that there are people in other countries who do not have Heating & Air Conditioning systems. In fact there are people who do not even have homes, & they do manage to survive. That is not how it works in this country, however! Here we must have Heating & Cooling in order to carry on each afternoon.Even our dog looks at me funny when I try to get her to transfer away from the heating vent!
