Quote from : Bertie's Guide to Life and Mothers Book

The value of money is subjective, depending on age. At the age of one, one multiplies the actual sum by 145,000, making one pound seem like 145,000 pounds to a one-year-old. At seven – Bertie’s age – the multiplier is 24, so that five pounds seems like 120 pounds. At the age of twenty four, five pounds is five pounds; at forty five it is divided by 5, so that it seems like one pound and one pound seems like twenty pence.
