Surely he has changed since April 2005 - as we all have!
However, I'd describe it more as a transformation into visible saintlyness, serenity, grace, infinite patience and gentleness.

Even when he might look strained and rushed, occasionally.
If I was in his position, I had bags under my eyes the size of North America.
