Is it too late to DB?

Not necessarily. MLC is a re-evaluation of one's life choices.

Everyone goes through some sort of midlife TRANSITION. It's only when they start destroying everything they've built in their lives that it becomes a CRISIS. Which is why depression doesn't have to factor in the equation all the time.

Plus there are different reasons for depression. It could be hereditary, it could be from guilt, pain or loss, etc. He could very well be expressing himself in a way that you don't typically define as depressed.
