London - Faced with adversity, many feel like they have the weight of the world on their shoulders.

Scientists at Cambridge University said this might be the brain’s way of exercising caution when life seems to be spinning out of our control.

The men and women then lifted boxes of books and estimated their weight. Finally, they answered questions about their mood.
