Recently I was given a DVD called "The Secret" by a close relative who strongly recommended that I watch it. I must confess, it sat on the shelf above the TV for the past few weeks and I was only reminded of it when someone else mentioned it to me recently. I watched it last night and I was intrigued and excited. I am really looking forward to testing out its claims.

In a recent study, John Bargh and his colleagues at New York University asked their volunteers to do a mental task involving words relating to old age, such as "wrinkled", "grey" and "bingo". A second group were shown words unrelated to old age. The researchers then said the experiment was over and secretly recorded the time each participant took to walk down the long hallway to the exit. Those with old age on their mind took significantly longer to walk down the corridor.

A optical illusion this month for you.

Stare at the dot in the center of the circle and then move your head closer to it. Neat!
