I just went past this again, you know, you might have thought they could have had one good looking or fit bloke, now I know age takes a toll on all
talking to yourself involves both sides of the brain,but it also veers towards multiple personality and personality disorder, people have a habit of talking to themselves when they feel no one bothers to listen to them, when they need someone to agree with them, talking out aloud is not necessarily talking to yourself though, sonetimes verbalising chores is a way your brain ticks off the steps. I personally would discourage talking to one self in young children just in case it leads to multiple ‘ split personality issues.
