     The time of year a baby is born can shape what profession they will embark on(从事) in later life,

a new study has suggested.

     Being born in a certain month appears to indicate the statistical likelihood of what job a person wil

l end up with, the study by the Office for National Statistics found.

     Researchers have uncovered that the month in which babies are born could also affect everything

from intelligence to length of life.

     A child born December is more likely to become a dentist while someone whose birthday falls in

January will tend to a debt collector, they found. A February birth appears to increase the chances

of being an artist while March babies appear to go on to become pilots. Meanwhile, April and May

are said to have a fairly even spread of professions, births in the summer months mean a much lower

chance of becoming a high-earning football player, doctor or dentist.

    The study was got by researchers who analyzed the birth months of people in 19 separate occupations

using information from the last survey, the Daily Mail reported. Although these trends may be difficult

to explain, correlations between birth months and specific health problems have a scientific basis.

     Spring babies are at greater risk of illnesses including schizophrenia, Alzheimer's disease, asthma

and autism.

     They may also be less clever than classmates born in other parts of the year.
