3. 0:10cat good catch granny I didn't know you
4. 0:14were
5. 0:15left-handed I was born
6. 0:18Lefty why did you know
7. 0:22lefty well let me handle that by
8. 0:25answering a question why are some of us
9. 0:29left-handed zoom
10. 0:31in today around 10% of the world's
11. 0:35population is Left-Handed also called
12. 0:40sinistrality which means you favor using
13. 0:43your left hand rather than your right
14. 0:46hand for everyday activities such as
15. 0:49writing lifting and at times even for
16. 0:52eating and unfortunately in many
17. 0:56cultures children are still forced not
18. 0:59to use their left hand as it's
19. 1:01considered wrong or
20. 1:04taboo maybe it has something to do with
21. 1:08the language used for both hands as
22. 1:11right is associated with being correct
23. 1:13or true while left in Old English means
24. 1:18weak and in Latin
25. 1:20Sinister not only that even everyday
26. 1:24tools such as scissors zippers openers
27. 1:28video game control rollers Etc are
28. 1:31designed to favor the righties and our
29. 1:35leftand fellows really have to struggle
30. 1:38to adjust in this rightand
31. 1:41world but the handy question is why are
32. 1:45they left-handed in the first place well
33. 1:49the answer to this question is still a
34. 1:51big mystery in the scientific Community
35. 1:55as we don't have the right answer but
36. 1:58only a few theories
37. 2:00yes and the well accepted theories state
38. 2:04that it has something to do with
39. 2:09genetics Studies have shown that
40. 2:12left-handedness is more common in
41. 2:14families with a history of
42. 2:18left-handedness if both of your parents
43. 2:21are right-handed you have a 10% chance
44. 2:24of being left-handed and if you have a
45. 2:28right-handed father and a left-handed
46. 2:30mother then there are 177% chance of you
47. 2:35being left-handed if it is the other way
48. 2:38around then the number goes up to
49. 2:4122% and in case both the parents are
50. 2:45left-handed then there is a 25% chance
51. 2:49of
52. 2:50it but then the vital question is how
53. 2:54did our forefathers become
54. 2:56left-handed well to know this let us
55. 2:59travel back in time when our ancestors
56. 3:02fought using heavy stones and Logs with
57. 3:05their right hands but eventually a few
58. 3:08of them trained to use the other hand to
59. 3:11get a Competitive Edge and took the
60. 3:14opposition by surprise and many experts
61. 3:17believe that this favorable left-handed
62. 3:21Advantage may have been passed down to
63. 3:24some people over the
64. 3:26years even today we may see this
65. 3:29phenomenal doing wonders in combat and
66. 3:32competitive sports like boxing and
67. 3:35baseball where left-handers known as
68. 3:38southpaws can shock opponents with their
69. 3:42unfamiliar moves but again why not a lot
70. 3:46of us use the left hand well according
71. 3:50to some experts it's due to the social
72. 3:53Cooperative activity of tool
73. 3:56sharing yes as we discussed ear
74. 4:00many of the vital tools that we use
75. 4:03every day are designed for right-handed
76. 4:06people and because left-handers are not
77. 4:10comfortable handling these tools and
78. 4:12often suffer from accidents they would
79. 4:15be less successful in a socially
80. 4:17Cooperative society and slowly vanish
81. 4:21out of existence keeping their numbers
82. 4:24at a minimum to maintain a healthy
83. 4:26balance of competition and cooperation
84. 4:30[Music]
85. 4:31but we still don't know the exact answer
86. 4:35however what we know is that some of the
87. 4:38greatest people to ever walk on earth
88. 4:41were and are left-handed and who knows
