Yes. (It seems increasingly likely, though, that a low level of damage
actually *helps*, by triggering the repair mechanisms to look for more
damage in an as-yet-unknown way. This makes adaptive sense, too; if
you've spotted damage repeatedly then the likelihood of your having been
hit with more damage that you simply haven't spotted yet goes up.)
And what on earth am I doing posting to this grossly off-topic thread?
