Glue is not stronger than wood.

Everyone likes to talk about how a good glue joint is stronger than thewood itself. I think this may be true in a very technical sense, butabsolutely false in practice.Take for example, a panel glue up with two 5" wide oak boards gluededge to edge (no biscuits, etc). There is no way in the world that thispanel is stronger than a single 10" wide piece of oak.If you whack the glued-up panel with a sledgehammer hard enough, itwill split along the glue line. It may take a little wood from eitherside of the joint, but is will definitely break right along the joint.Conversely, the solid 10" wide piece of oak will certainly withstand aharder blow without breaking than would the glue-up panel.What am I missing in this 'glue is stronger than the wood itself'argument?

Then they found out flaked flint caused cancer. So it was back to the bone tools for us...

They didn't want us to work it because so many of us blinded ourselves with the chips. Dangerous stuff that flaked flint.

The micron-sized particles caused silicosis.

Is that the disease one would get from inhaling too deeply near Pam Anderson's chest?

No. In a case like that, you'd probably get punchinthenose itis.
