AT this time of a new year it is always as well to ensure your mental capacities have not been weakened by excessive celebration during the festive season.

So here is a short, four-question test to confirm your brain is still working all right.

1. What do you put in a toaster?

Answer: Bread.

If you said toast give up now and do something else. Try not to hurt yourself.

2. Say ‘silk’ five times. Now spell ‘silk.’ What do cows drink?

Answer: Cows drink water.

If you said ‘milk’ please don’t attempt the next question.

Your brain is over-stressed and may overheat.

3. If a red house is made from red bricks and a blue house is made from blue bricks and a pink house is made from pink bricks and a black house is made from black bricks, what is a green house made from?

Answer: Greenhouses are made from glass, of course.

If you said ‘green bricks’ go and have a lie down.

4. This last question should be done without using a calculator.

You are driving a bus from London to Milford Haven in Wales.

In London, 17 people get on the bus.

In Reading, six people get off the bus and nine people get on.

In Swindon, two people get off and four get on. In Cardiff, 11 people get off and 16 people get on.

In Swansea, three people get off and five people get on.

In Carmarthen, six people get off and three get on. You then arrive at Milford Haven.

Without scrolling back to review, how old is the bus driver?

Answer: You are going to kick yourself for this if you get it wrong as the clue’s more than there in the question.

Don’t you remember your own age?

It was you driving the bus.
