Re: "To run is good exercise"?!

Summarizing the findings so far (19-Jan 17:35 GMT), these counterexamples have been given:

(A)
To err is human

(B)
To provide a counterexample, - -
To be honest, - -
To bring that question up now - -
To have lunch with you is - -
To be rude - -
To run all the way would - -
To see one is to know one - -
To be a nurse would - -
To have a car - -
To say that would be wrong

Strange but I see a pattern here. If the sentence-initial infinitive does not have a complement phrase(s) as all the examples in the B group, it has to be the subject of a predicative clause ending in an AP, as in the A "group".

Hey, that really was a glove that struck you! Now give counterexamples to counter this.
