Tony Keenan, professor of organisational behaviour at Heriot-Watt University, has been explaining how you check for Type A personalities, one of the predictors of future career success among undergraduates. At lunch, check who finishes first - the winner will also be a winner at work. But the downside, Professor Keenan warned, is that Type As are also six times more likely to have heart attacks.

Clearly what is now needed is research on the link between heart attacks and bolting your food.
