Which hand do we Seniors use for writing who live at Brookdale Assisted Living in Oswego Springs, Portland, Oregon? In other words, which hand belongs to people living the longest? Studying the menu sheet is serious business with many here. This is serious, picking and writing down notes to the chef in order to get just the right food.
Today I noted that all 4 women at my table were left-handed upside-down writers just like me! It was unbelievable! Yes, being a left-handed "upside-down" (or hooked/inverted) writer is much more rare than simply being left-handed. While roughly 10% of the population is left-handed, inverted writing is a specific posture adopted by only a subset of that group, often to avoid smearing ink or because of how they were taught
Such a group of women, too!!! Gender: Left-handedness is slightly more common in males (approx. 11% in some studies) than females (approx. 8%). This one day just happened to have 4 of us together; left-handed upside-down writers writing away!!! I could not believe my eyes. Also strange was that 3 of us were ladies at one time or another this year trying to learn to play Mah Jongg (also spelled Mahjong).
Left-handedness is a natural, often genetic, trait in about 10% of the population, defined by a dominant left hand for daily tasks. While often navigating a world designed for right-handers, lefties possess unique brain connectivity that may offer advantages in sports, creativity, and spatial tasks. Studies show a significantly lower prevalence in older generations, often between 3% and 6%, due to historical cultural pressures that forced children to become right-handed. They tried to change me, but I was a stubborn lefty.
Something we can't do in Portland, as it rained all morning; we eat in the dining room. Today was an exception. One of our ladies never came down for lunch so her seat had become occupied by another who liked to move around from table to table to get to know more people. Another rarely came for breakfast as she liked to sleep later, being a midnight TV-watcher. We have the rule, first come, first seated. If you're late, you take a different seat. There's no saving seats for people. After a little appeasement and adjustment, we all settled down.
Here we sat for the first time together; Sandy from San Francisco, California, Teddy from Duma, Texas, Geri from Brooklyn, New York, and myself from Portland, Oregon. How we all came together at the ripe old ages of 32 said a definite senior, to 78 to 82 and me at almost 92 must hold a lot of exciting adventures. Brookdale can handle us all!
Based on 2026 demographic projections, there are approximately 35 to 55 million left-handed people between the ages of 70 and 79 worldwide. Total Population Age 70-79: The global population of people aged 60–79 is roughly 918 million, with the 70-79 subgroup representing a significant portion of this.
Based on global demographic trends for 2026 and studies on handedness, it is estimated that there are a few million self-identified left-handed people between the ages of 80 and 89 globally. Total Population (80-89): As of 2026, there are over 150 million people worldwide aged 80 and older. Left-Handed Prevalence in Elderly: While 10–12% of the general population is left-handed, studies indicate that for individuals aged 80 and over, the reported prevalence is significantly lower, often less than 1% to 5%.
Based on global population estimates for 2026 and studies on handedness, there are estimated to be roughly 1.5 million to 2.5 million left-handed people between the ages of 90 and 99 worldwide.Total Population (90-99): As of 2020, there were roughly 147 million people in the 80–99 age bracket. Projecting this to a narrower, older, and smaller 90-99 bracket in 2026, it is reasonable to estimate a population of roughly 100-150 million, though exact numbers are difficult to pinpoint.
- Left-Handed Percentage (Old Age): While roughly 10% of the general population is left-handed, this percentage drops significantly to under 1% or roughly 1.67% in studies of those older than 80.
- Calculation: Using a conservative \(1.5\%\) of 150 million, the number is approximately \(2.25\) million.
Do left handers die earlier? Nada's answer: Our genes of handedness comes from our paternal grandfather who died in a horse and buggy accident: I'm left-handed alive and 91years and 7 1/2 months old; my brother, David was left-handed and died at 81 years 2 months 6 days; our 1st cousin by male line Nate, another lefty died at 86 years 2 months 1 day.
Data are presented on the prevalence of current left-handedness and prior left-handedness (switched) in 2787 subjects from 21 to 101 years of age. In addition, data on sex differences, familial sinistrality, hand posture when writing, and education were recorded. Two hypotheses were tested.
The elimination hypothesis states that reduced frequency of left-handers in old age is due to reduced longevity.
The modification hypothesis states that differences in the number of left-handers between older and younger persons are due to changing patterns of social norms.
The results showed a decreasing prevalence of left-handedness across the age span, with 15.22% in the youngest group (21-30 years), but only 1.67% in subjects older than 80 years. There was however a corresponding increase in the number of subjects who had switched hand for writing, 2.69% in the youngest group to 6.75% in subjects 80 years and above. (You go back in history and it was common to force people to switch)
This supports the modification hypothesis and questions the elimination hypothesis. However, the mean percent score was still lower in subjects above compared to below age 40 after correction for hand switching. Thus, although changes in social norms towards left-handers seem to be the most likely explanation, we have not empirically disproved the elimination hypothesis. WELL!!!!!
People have concluded many things about lefties, but I like this one best: In his book Right-Hand, Left-Hand, Chris McManus of University College London argues that the proportion of left-handers is increasing, and that an above-average quota of high achievers have been left-handed. He says that left-handers' brains are structured in a way that increases their range of abilities, and that the genes that determine left-handedness also govern development of the brain's language centers.
