Well Pete my dad always told me never to belive what you read in a newspaper, and I have added a bit onto this for my children, "in particular the sun".

Well a bid tough guy like Harmison is not going to admit he let being home sick spoil his form, and if he believes that himself, I wonder what is between his ears, you suffer with home sickness, you can't in my opinion turn it on and off, it would get on his nerves, like anyone else.
By what he is saying, he does not get home sick when playing cricket (when his mind is occupied), so what about when he was out with his mates playing golf, in the bar ect.

If he is telling the truth (which I doubt), they he is one **** bowler to bowl so poor in every match in South Africa, taking the heat into consideration as well.

BTW, well spotted in the Sun .
