What happened 73 years ago is worth studying as is what happened 173 years ago.

Why?

Patterns my friend.

Things happen repeatedly.

Not the same things, but things that represent the same effect and results.

There are though, a few outlying rare unique and original ruffles and disturbances. They, can be good and they can be bad. Watch for them too.

And moral – if needed – of the story may be “Be fleet-footed, be flexible”.

Whatever that may be!
