The average person forgets four important facts, items or events every day, it has been revealed. Researchers who carried out the study among 2,000 adults found we typically forget as many as 1460 things every year, including leaving for work without a phone, keys or wallet or forgetting what you went into a room for.

The study compiled the top 50 most commonly forgotten things and found important messages, meetings and emails are also missed amid our busy lives.

Forgetting to defrost meat or where you parked the car are common slips, while the dreaded lapse in remembering someone's name when introducing them was a regular blank.

A spokesman for the Post-it Brand from 3M, which commissioned the report, said:

''Our days are so jam packed full of tasks whether at work or at home, it's no surprise people find it hard to keep track of everything.

''With much longer working hours, financial concerns and just busier lifestyles, even those with the best memory can stumble when it comes to remembering even the most simple of things during a hectic day.''

Women were found to show the most frustration when they lose or forget things - yet men are twice as likely to forget a partner's birthday or an anniversary and, remarkably, one in twenty men have completely forgotten to attend a funeral.

 

"I know today is important... I just don't know why..."

Indeed, more than half of women in relationships said their partner has forgotten something they were counting on them to remember despite numerous attempts to remind them.

But the ladies aren't always perfect, and are actually more likely to lie if they've forgotten something big and think they'll get in trouble for it - one in four women admitting to doing this.

Men are also slacker when it comes to passing on important messages, and perhaps this explains why women were twice as likely to be the one in the relationship with the better memory.

No surprises then that 54% of men in relationships rely on their partner to remember certain things so they don't have to.

While a quarter of the women studied said they can never rely on their partner to do something if it's crucial and are better off doing it themselves.

An embarrassed one in five dads has completely forgotten to pick up the kids from school.

Which goes some way to explaining why men were nearly twice as likely to have been labelled a 'liability' when it comes to being organised.
