Which birth month has the lowest life expectancy?
In general, individuals born in May through July had the lowest age at death (1984: 75.27+/-0.09 years; 1999: 77.58+/-0.09 years), while those born between October and December had the highest (1984: 75.98+/-0.08 years; 1999: 78.35+/-0.09 years), supporting earlier findings.
They Live the Longest
While October babies have the highest risk of disease among all birth months, they don't let that stop them from living very long lives. According to a 2011 study of over 1,500 centenarians (or people that live to be 100), babies born between September and November live the longest.
The least common birthday is leap day, or February 29. But because the day only occurs once every four years, it's obvious it would yield the least amount of birthdays. The rarest birthday of the 365 annual calendar days is Christmas day, Dec. 25.
“May, June and July … seemed to be a better time to give birth,” Boland says, when it comes to babies' overall disease risk. Women's own birth month seems to be linked to their reproductive health, too, with those born in October and November at highest risk for some childbirth complications like false labor, she says.
The Least Common Birthdays
December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common. December 24 (Christmas Eve) also makes the list as the 3rd least common birthday while July 4 (Independence Day) is the 4th least common birthday.
But a statistical study of centenarians by researchers at the University of Chicago has found some other potential predictors of extreme longevity. Women and men who were the first born in large families, the study found, were two to three times more likely to make it to 100 than later-born children.
Abstract. Month of birth influences adult life expectancy at ages 50+. Why? In two countries of the Northern Hemisphere–Austria and Denmark–people born in autumn (October–December) live longer than those born in spring (April–June).
First, it might be reassuring to parents that, at least when skills are measured at a young age, month of birth doesn't appear to have a major impact on intelligence or academic performance; seasonal differences seem to be related more strongly to instructional experience (individual attention provided, age of school ...
You know the ones I am talking about — the ones that end in a zero. The ones that make you happy when you are young, happy that you are getting older, can do more, be more. The zero birthdays as you get older that make you stop and think about your future, your life, your family, your mortality.
Sixty percent of babies are born during the day, between 6 A.M. and 6 P.M. And, 3.5 times as many babies are born at exactly 8:00 A.M., the most common minute to be born, than at the least common, 3:09 A.M.
What month are the smartest born?
Those born in September are, apparently, the smartest out of the entire year. According to Marie Claire, a study published in the National Bureau of Economic Research found that there's a clear correlation between the month during which you were born and how smart you are.
The new study, which was published in the Journal of American Medical Informatics Association, concludes that people born in May have the lowest overall risk for disease, while people born in October have the highest.
Birth data shows that Sept. 9 is the most common birthday in the U.S., and September is the busiest month for births overall. There have been several reported data sets that offer a picture of which days and months are the most common for births.
In concluding the study, co-author and psychologist at the University of Padova in Italy Paola Bressan noted that to the best of her knowledge, “no study has either replicated or supported” the findings from the 1995 study that stated babies resemble their fathers.
Firstborn children are taller compared to those born subsequently, and this height advantage increases sharply over the higher order of birth of siblings.
We are born in the flesh, and then we are born again spiritually. Our first birth is cursed because we are all “shapen in iniquity; and (born) in sin” (Psalm 51:5) and because of this, we cannot receive the blessing of Father God.
The Sign Eviota, Eviota sigillata, a tiny coral reef fish, completes its entire life cycle within an eight week period. This species has the shortest lifespan of any vertebrate.
The mortality rate is very low during childhood, then increases exponentially from age 30; it is lower for females at all ages.
#1: Mayfly — The Shortest Lifespan of Any Known Animal
These insects are the shortest living animals on the planet, as the adult lifespan of a fly from this species is only 24 hours.
