I have seen this expression, "perfectly healthy" referenced in this list
several times (most recently in the discussion "Latest Sheffield News," a
matter I have zero knowledge about).

Failures of "perfectly healthy" trees are a too-common occurrence here in
the US. Perhaps the most common cause is "heartwood rot," where the cambium
remains healthy, and there are no *outward* signs of decay--at least no
obvious ones. But there's the rub--is* "casual" *inspection good enough?
Some signs of internal decay can be very subtle--and in my younger years I
undoubtedly missed a lot of them. In fact, I just recently learned about
one I had missed forty-seven years ago. Tree "expert?" I fear the term. A
pity that hubris is the prime rot of our societies. Sad. (I'm joking, I'm
joking!)

Here is a classic case:

I solicit your comments. (Please advise me of any present, past, or future
instances of bad form on my part.)
