New photo Why it's harder to lie as you get older: Elderly people are unable to tell a convincing fib

Old people lack the mental ability to lie convincingly, scientists have found. 

The decline in cognitive function due to ageing means they are unable to keep track of their falsehoods. 

A study has found that 20-year-olds are far better at maintaining a web of deceit and lying convincingly than 70-year-olds.

Researchers from Brandeis University in the US published the research in the journal Brain and Cognition.

Brain recordings taken using an electroencephalogram (EEG) found that millennials and the elderly had similar responses when telling the truth. 

However, the brain of a pensioner was noticeably less able to cope when the person was asked to lie.

The study's authors suggest in the paper that this means lying requires significant brain power and cognitive control.

This higher level of mental capacity has been known to decline as a person ages. 

Participants in the study were asked by researchers to lie by falsely describing something they hadn't seen.

They were divided in two two groups - young and old - with a median age of 75 and 20.

This untruthful process relies heavily on complex mental processes to create a believable untruth, which is more challenging for older people.

For grannies hoping to get away with a fib, the repercussions of lying may far outweigh the benefits of a little white lie. 

However, the study's authors note that lying by denial (feigning amnesia, for example) may be less taxing on the brain.

WHAT IS AN EEG AND HOW DOES IT WORK?

An electroencephalogram (EEG) is a recording of brain activity which was originally developed for clinical use.

During the test, small sensors are attached to the scalp to pick up the electrical signals produced when brain cells send messages to each other. 

In the medical field, EEGs are typically carried out by a highly trained specialist known as a clinical neurophysiologist.

These signals are recorded by a machine and are analysed by a medical professional to determine whether they're unusual.

An EEG can be used to help diagnose and monitor a number of conditions that affect the brain.

It may help identify the cause of certain symptoms, such as seizures or memory problems.

More recently, technology companies have used the technique to create brain-computer interfaces, sometimes referred to as 'mind-reading' devices.

This has led to the creation and design of a number of futuristic sounding gadgets.

These have ranged from a machine that can decipher words from brainwaves without them being spoken to a headband design that would let computer users open apps using the power of thought.

To achieve her kick-ass figure, Hayden – who plays cheerleader Claire Bennet in Heroes – follows the ‘quartering’ rule. She eats only a quarter of the food on her plate, then waits 20 minutes before deciding whether she needs to eat again.

Hayden says: “I don’t have a model’s body, but I’m not one of those crazy girls who thinks that they’re fat. I’m OK with what I have.”

Nicollette says: “I don’t like diets – I see it, I eat it! I believe in eating healthily with lots of protein, vegetables and carbs to give you energy.”

SATC star Kim swears by gym sessions with Russian kettle bells (traditional cast-iron weights) and the South Beach Diet to give her the body she wants. To avoid overeating, Kim has a radical diet trick – squirting lemon juice on her leftovers – so she won’t carry on picking.

Kim says: “I am no super-thin Hollywood actress. I am built for men who like women to look like women.”
