comment out unused health variable

Code review

That's scarcely an improvement. Chunks of commented out dead code wouldn't pass muster in many code review processes. Keeping them around is what the VCS is for. In this case, the dead code is trivial and at best the comment reflects some nebulous future intent to do something (maybe) in the future with it. We'd have to cut open dumbo's head and analyse it carefully to know.

In other words, deleting the line would be better.

Was there nothing else wrong with it all? I don't want to have to look at a series of PRs on this. Gather up all the code quality changes in on big PR please.
