You may have noticed that I spend quite a lot of my time explaining why something is a bad idea and should be treated with caution. Occasionally this has resulted in complaints that I keep pouring cold water on everything. The best response to this comment is one I first heard many years ago:
“Cold water is the natural result of hot air meeting thin ice”.
