How Small?

So I renewed my library card a couple of weeks back and have since checked out a few books on dust collection that the library had.

Now I know we all talk about dust collection and how small particles are bad for us. 10 micron, 5 micron, 1 micron...yada yada, but words don't always compute for me, I'm some what of a visual person sometimes.

Anyone else relate to this?

So here is a visual I came across in the book "Collecting Dust in the Workshop", by Rick Peters, with a comparison to a human hair...

That image reminds me of the picture shown to me in 1982 relating smoke hair and dust particles to the gap between the head and platten on a hard drive motivating a clean room for the Dec Vax computers we had. Lol. Flashback.

Sure puts it into perspective for me. Does make u wonder about all sorts of normal dust in the home especially the amount of general lint coming off clothing given the tumble drying.
