Now we've got another gene to blame!

Did you see the article in a recent newspaper that says if we have the ability to keep "cool, calm and collected" when others around us are having tantrums, temper blasts and "losing their heads", then we can thank our parents?

It seems studies in Germany at the University of Bonn asked more than 800 people on how they handled anger. Their DNA's were tested to determine which of three versions of a gene affecting depression levels they carried.

Those with one version were significantly "cooler" than those with the others. Angry types also had less grey matter in the brain's emotional centre. (Behavioural Brain Research)

While talking about "grey" matter - oh, how Agatha Christie loved this subject - it seems from studies here in Australia that teenagers who are binge drinking are opening themselves to all sorts of brain malfunctions, now and in the future, in that their levels of "white" matter are decreasing rapidly.

This brought about a question amongst our group this morning - just how many different coloured "matters" do we actually have in our brain?

Would that account for some people having black and white dreams while others always have technicolour?
