Oh, you guys are too funny! First thread here thats has made me laugh.
I avoid ladder, because I am over 60 and deeply fear falls. Sometimes, I DO have to use one, and when I do, I take it very slowly and very carefully. In Florida, everyone has ceiling fans, which are a royal pain to clean unless you use a ladder. Its kinda amazing how much dust can accumulate on fan blades in just a short time. And also, kinda disgusting! If you know what dust actually is made of, its even more gross. LOL! Human skin cells, animal skin cells, dander, dead dried up insects, hair, ordinary dirt and who knows what else. We MAKE our own dust, in case you didnt know this. The older a building is, the more dust. In an old building much of the dust is from PREVIOUS occupants and their pets. But a brand new home also has dust.
In one of my science classes for my Nursing degree, we looked at our own home's dust under a microscope. It was VERY interesting and also a bit disgusting. LOL!
