People Born in Autumn Live Longer People born in the autumn live longer than those born in the spring and are less likely to fall chronically ill when they are older, according to an Austrian scientist. Using census data for more than one million people in Austria, Denmark and Australia, scientists at the Max Planck Institute in the northern German town of Rostock found the month of birth was related to life expectancy over the age of 50. Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new-born baby and could influence its life expectancy in older age. "A mother giving birth in spring spends the last phase of her pregnancy in winter, when she will eat less vitamins than in summer," said Gabriele Doblhammer, one of a team of scientists who carried out the research. "When she stops breast-feeding and starts giving her baby normal food, it's in the hot weeks of summer when babies are prone  to infections of the digestive system." In Austria, adults born in autumn (October-December) lived about seven months longer than those born in spring (April-June), and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture was similar. Adults born in the Australian autumn--the European spring--lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition at all times of the year has improved since then, the seasonal pattern persists, Doblhammer said. But on the other hand, according to a study of more 40,000 people, those born in spring and summer report themselves luckier than those born in autumn or winter. Professor Richard Wise-man who led the research explained that the temperature at the time of birth might influence the development of the brain and seasonal factors make a difference as well. The right sentence of the following is   _  .
The month of birth was not related to life expectancy over the age of 50. A mother giving birth in spring spends the last phase of her pregnancy in winter, eating more vitamins than in summer. Stopping breast-feeding and starting giving babies normal food must make babies prone to get infected with the digestive system in the hot weeks of summer. Adults born in the Australian autumn--the European spring--lived about four months longer than those born in the Australian spring.
