why some people are right handed and some left handed? if it's because of the side of brain that control their motions, why some people are left handed but right foot or vice versa?
When I make a post like that in the Biology or General Physics section I always get busted and my post gets deleted. Ha ha ha... this one time, I said people that are shorter, are shorter because the air pressure in their geographic location, is higher. Or just yesterday. Somebody asked about static and their hair, and their comb. I said "don't forget to take the batteries out of your comb." Bah! DELETE! :grumpy:DaveC426913 said:It is the advancement of humans through evolution. Left-handers are not only surviving, but their numbers are on the increase. This clearly demonstrates that they are superior. They are also more intelligent, better-looking, get hotter dates and find more winning prizes under the caps of pop bottles.
Befriend a lefty. Buy him lunch. It may just save your life one day.
The exact cause of handedness is not fully understood, but it is believed to be a combination of genetics and environmental factors. Studies have shown that approximately 25% of handedness is due to genetics, while the remaining 75% is influenced by environmental factors such as brain development and cultural influences.
It is possible for a person to switch their dominant hand, but it is not a common occurrence. This change is known as "cross-dominance" and can happen due to a neurological injury or as a result of training and practice.
There is a common stereotype that left-handed people are more creative, but there is no scientific evidence to support this claim. While some studies have shown a higher percentage of left-handed individuals in certain creative fields, it is not a direct correlation and may be influenced by other factors.
Left-handed individuals may face certain challenges in a world that is predominantly designed for right-handed people, such as using right-handed tools or struggling with handwriting. However, with practice and adaptation, left-handed people can learn to navigate these challenges effectively.
There is no known link between being left-handed and any specific health conditions. However, left-handed individuals may be at a slightly higher risk for certain neurological conditions, such as dyslexia and ADHD, due to the way their brains are wired.
