Looks like you are right. Something changed. It's like he went from being an extrovert to being and introvert. Have you seen more recent photos of him where he with other people? I don't think I have.
yes that's another thing, he always took pics with other people now he is always by himself with a stone face
i guess it just goes to show the more you pursue bodybuilding the more lonely a pursuit it is, other people want to get together and drink alcohol while he's drinking protein shakes and the average person just views the sport as strange so he doesn't fit in any more
maybe a mid life crisis too, who knows?
