Just because something hasn't been proven one way or the other doesn't mean you should just believe either of them on a whim.

It's totally okay to hold beliefs tenuously and then not feel attached to them when they're proven wrong.

It happened to me here in this thread. I stated cows milk leeched calcium, but it doesn't, I was misinformed. There's no shame in admitting I was wrong, but it reminds me to be more cautious about assertions of fact in the future.

I don't want to be wrong any longer than I need to be.
