Thought your star sign was the only thing determined by your birth month? Well think again, because when we are born has a bigger impact than many of us realise.
Scientists from the University of Colombia have developed an algorithm to explain the relationship between month of birth and risk of disease.
They say your risk of a heart attack is higher if you were born in March and you are less liable to chronic illnesses if you were born in May – though they emphasise that lifestyle, diet and exercise are more important.
It’s the latest in a string of studies to show ow your birth month affects your life – everything from how well you do at school and your career choice to your overall happiness.
So what does your birth month say about you?
January babies include Kate Middleton, 33, Gary Barlow, 44, and 70-year-old rocker Rod Stewart. But they seem to be the exception rather than the rule. For instead of Royals and musicians, the Office for National Statistics (ONS) says if you’re born just after new year, you’re more likely to become a GP or a debt collector.
Those born in January are also at higher risk of developing Alzheimer’s, Crohn’s disease or epilepsy, research has revealed.
But beware – February also produces a high number of traffic wardens, according to a study by the ONS which analysed the birth months of people in 19 different professions.
When it comes to health, researchers from the University of Colombia in New York say people born in February are also more likely to die from lung or bronchial cancer. The researchers are hoping the data will now help them to uncover new risk factors for certain diseases.
Lady Gaga, 29, sang she was Born This Way, and Theo Walcott, 26, is certainly fleet of foot, so it may be no coincidence that being born in March makes you a high flyer – quite literally, as there is an above average number of pilots born this month.
But there is also a spike in the number of March-born people suffering from particular forms of heart disease, which scientists believe may be down to fluctuating levels of vitamin D.
It is however a poor month for future health issues, with people born in April more likely to suffer from autoimmune diseases and non-hodgkins lymphoma.
Statistics show there’s also higher numbers of April babies becoming alcoholics and developing eating disorders.
Babies born in May are the biggest – an average of 7oz heavier, according to a study.
But they also have the lowest chance of captaining England at sport – David Beckham being the exception.
The upside for May babies, like Lily Allen, 30, and 89-year-old David Attenborough, is that the University of Colombia study found that they have a lower risk of suffering from chronic illnesses during their lives.
Prince William, 32, and Michelle Keegan, 28, have both been spotted wearing specs. And a study found that summer babies like them can have an increased risk of suffering vision problems later in life, which researchers think may be down to lack of exposure to sunlight during the early stages of their development.
But being born in June could be the recipe for success – there is a higher percentage of Nobel prize winners born this month. While it is not known why, because of the structure of the school year, all June babies start school when they are four, as opposed to nearly five for Autumn babies.
Peter Kay, 41, certainly knows how to make other people smile, and research has shown that July born babies like Peter, Jeremy Kyle, 49, Lindsay Lohan, 28, and Tom Cruise, 52, are more likely to be more optimistic than those born in winter.
This sunshine month also has a spike in the number of train drivers and bricklayers celebrating their birthdays.
But people born this month are more also likely to have autism or asthma, according to studies. Researchers believe that certain types of asthma can be linked to a newborn’s exposure to dust mites in their first few months of life – and mites thrive most in the warmer months.
August babies are at a disadvantage from the day they start school – they are the youngest in the class. Teachers are also 30 per cent more likely to label them as “problem” students according to the UK Institute for Fiscal Studies. But being born in August certainly didn’t hinder President Barack Obama.
Fearne Cotton, 33, and 50-year-old Keanu Reeves may have been top of the class at school. September-born babies tend to be the highest achievers having almost a whole year advantage on their pals born in July and August, and they are also the most likely to go to University.
Autumn born babies are more likely to reach the grand old age of 100 than those born at other times of the year.Scientists are still unsure as to why, but believe it could be connected to different seasonal infections babies are subjected to in their first few months which could leave different amounts of long-term damage.
Research by Essex University found that children born in October and November were fitter, stronger and more powerful than their peers born in the other 10 months of the year. They have theorised that it could be because their mums were exposed to more vitamin D from sunlight in the last months of pregnancy.
October however is also said to be the worst month to be born for possible health problems, with people born this month at higher risk from insect bites, STIs and chest infections.
Jimi Hendrix was left handed – and research has shown that men born from November to January are more likely to favour their left hand than people born in other months.
But there are also more serial killers are born in November than any other month, according to a study.
Those born in November are also most likely to believe they get a raw deal. A 2005 study found that they grow up to be the most pessimistic.
But there is some good news for November babies Kendall Jenner, 19, Gordon Ramsay, 48, and Caroline Flack, 35, – people born this month are less likely to suffer from heart problems or lung cancer.
There is also an above average number of dentists born this month.
But winter babies were more likely to have less-educated mothers, according to a statistical study in the US.
