Veering sharply off-topic, that reminds me of the plastic clothespin
that snapped and cut my hand. A wooden clothespin will also be
destroyed by exposure to sunlight, but when it fails, it just sighs
and gives up.

I haven't seen plastic clothespins in the stores recently.


Here, I don't believe that I've ever seen a wooden clothespin.
Everything seems to be plastic these days.
I just asked my wife about wooden clothespins and she said that she
remembers them from when she was a little girl, 5 - 10 years old.

I've got a mouthful of plastic that got stronger when exposed to
ultraviolet. I don't expect to test its resistance to sunlight -- I'm
not *that* happy a cyclist!
