[Music] C cat good catch granny I didn't know you were left-handed I was born Lefty why did you know lefty well let me handle that by answering a question why are some of us left-handed zoom in today around 10% of the world's population is Left-Handed also called sinistrality which means you favor using your left hand rather than your right hand for everyday activities such as writing lifting and at times even for eating and unfortunately in many cultures children are still forced not to use their left hand as it's considered wrong or taboo maybe it has
something to do with the language used for both hands as right is associated with being correct or true while left in Old English means weak and in Latin Sinister not only that even everyday tools such as scissors zippers openers video game control rollers Etc are designed to favor the righties and our leftand fellows really have to struggle to adjust in this rightand world but the handy question is why are they left-handed in the first place well the answer to this question is still a big mystery in the scientific Community as we don't have the right
answer but only a few theories yes and the well accepted theories state that it has something to do with genetics Studies have shown that left-handedness is more common in families with a history of left-handedness if both of your parents are right-handed you have a 10% chance of being left-handed and if you have a right-handed father and a left-handed mother then there are 177% chance of you being left-handed if it is the other way around then the number goes up to 22% and in case both the parents are left-handed then there is a 25% chance of
it but then the vital question is how did our forefathers become left-handed well to know this let us travel back in time when our ancestors fought using heavy stones and Logs with their right hands but eventually a few of them trained to use the other hand to get a Competitive Edge and took the opposition by surprise and many experts believe that this favorable left-handed Advantage may have been passed down to some people over the years even today we may see this phenomenal doing wonders in combat and competitive sports like boxing and baseball where left-handers known
as southpaws can shock opponents with their unfamiliar moves but again why not a lot of us use the left hand well according to some experts it's due to the social Cooperative activity of tool sharing yes as we discussed ear many of the vital tools that we use every day are designed for right-handed people and because left-handers are not comfortable handling these tools and often suffer from accidents they would be less successful in a socially Cooperative society and slowly vanish out of existence keeping their numbers at a minimum to maintain a healthy balance of competition and
cooperation [Music] but we still don't know the exact answer however what we know is that some of the greatest people to ever walk on earth were and are left-handed and who knows some of our left-handed viewers will someday be on this unique list too trivia time did you know August 13th is celebrated as International left-hander Day yes the purpose of this day is to raise awareness of the unique challenges that left-handed people face in a right-handed World sketching time today's sketch of the day goes to 10 years old Amisha upad hope you had fun today
until next time it's me Dr boox zooming out [Music] never mind [Music]
