You hear a great deal about global warming these days.
Some people say it threatens life on Earth, others say it is nothing but a myth.
Me, I don't know anything about that either way. What I do know about is global cooling. Now there is something that has really changed our lives over the last 40 years. Maybe it has warmed up a few degrees on the outside during that time and, if so, that's a terrible thing. I know for sure, though, that it has cooled down by 20 or 30 degrees on the inside.
