There is no difference in life expectancy between left and right handed people. There was a controversial study done in 1980 by Halpern & Coren that suggested left-handed people had an average life expectancy of 9 years less than right-handed people. However, data was based on second-hand information: surveys from the next-of-kin of recently deceased persons asking about right/left handedness and age of death. They found left-handed average age of death was 66; right-handed average age was 75.
Unfortunately, this study keeps getting quoted even though more recent data has shown their hypothesis is not supported. Second hand survey data is not a sound methodology.
In addition, if a study reports a higher mortality rate (or any other "problem") in left-handers, then it's very important to look at the research design and how the data was analyzed. Simply checking the sample sizes will give a good indication of whether it was a "real" significant difference. If the sample sizes are large, and most studies have sample sizes of 1,000 or more, then there will be a "statistically" significant difference between groups (i.e.: Left versus Right) even if the amount of variance explained by the two groups is very small, which means there is no clinical significance. A statistical significant difference does not mean it has clinical or meaningful significance. Many statistical tests will give a significant difference only because of large sample sizes. Therefore, the measure of explained variance needs to be computed because it is unaffected by sample size.
More recent studies have disputed the notion that left-handed people die earlier. For example, see the study by Aggleton, Bland, Kentridge, & Neave in the British Medical Journal at http://bmj.bmjjournals.com for more information.

Roughly 50%, the same as the percentage of people who are women overall.
Not anymore...Ruth is deceased. Ruth both pitched and hit lefthanded, so he probably wrote with this left hand, but maybe not. Many lefthanded people write with their right hand.
The average life expectancy of people is higher than it was in the past. People who are homeless are known to have a lower life expectancy.
When a country has a lower life expectancy than another one it basically means that people, on average live for a shorter time than in that other country as a life expectancy of a country is the average time you can expect a person to live for. Generally, a woman's life expectancy is slightly higher than a man's by about 2 or 3 years. Japan currently has the highest life expectancy with people there enjoying an average of 84 years. Sierra Leone is currently on the other end of the scale, with people there living for just 46 years.
Yes. Schizophrenics have a life expectancy of 12-15 years less than other people. This is because of a high suicide rate (4.9% of schizophrenics commit suicide), drug use associated with schizophrenia, and increased rate of obesity in schizophrenics.
Life expectancy at birth is 74%.
The life expectancy of a person with autism is the same as you and I.
51 years for both men and women is the life expectancy for people in Nigeria.
The life expectancy with someone with carcinoid lung cancer depends on the stage of the cancer. For people with stage 1, the life expectancy is 93%. For people with stage 5, the life expectancy is 57%.
There is a saying my grandmother said to me, as I was lefthanded. "lefthanded people owe the devil a days work". I believe this has some reference to the devil, before being cast out, sat on Gods left hand. I'm not sure where it goes from there. Peace
People in Australia would expect to have a higher life expectancy than people in Africa. There are lots of very well developed parts of Africa where people would have a high life expectancy, but on average it would have a lower life expectancy.
There are 181,471,834 people in Germany. The life expectancy for males is 78 years and the life expectancy for females is 82 years.
Yes those people were a lit shorter.
People with Fragile X syndrome have the same life expectancy as unafflicted people.
The life expectancy in the United Kingdom is 78.85.
The life expectancy for Liberia is 38.9 male and 41.9 female.
yes,shorter people do have more energy then taller people.
The 2009 life expectancy of Zimbabwe is 39 years and 3 months.
Normally, people recover fully from chickenpox and it does not affect life expectancy.
Alphabet is signed by making the 'A' then 'B' then 'C' on your hand moving slightly to the right for righthanded people. See the link below...
No, coffee does not make people shorter its just a wise tail
