Jaal recently told me that if you rev a modern engine too high, a
"governor" kicks in and stops you from revving the engine even higher,
so you won't destroy it. I was looking at a beautiful waterfall
yesterday, amazed how it wrapped under the bridge we stood on, when I
felt my elation tempered by the always-present fact that Lev was not
here to see it. Emotional governance. It puts a cap on all joy.
