Is the left-handed person really smart?

Firstly, I am so glad that the admin give me the chance to publish what I write here. Certainly, I also need to thank those readers who are reading my topic this moment on this forum. Today, what I want to chat is the left-hander; I believe that some of you must have met the left-hander around. So is the left-handed person really smart as we think?

Yesterday, when I shopping in discount golf clubs, my intention was to buy the new golf irons, certainly, I speak of the online shop not means advertising here, this shop was recommended by my friend, Left Hand Callaway RAZR X HL Irons, the new item which was brought in December, some comments here caught my attention, and I began to ask myself: “Is the left-handed person really smart?” according to Google, I get to know the most famous 10 left-handed person，such as, the America president Obama，The French President Napoleon, and my idol Marie Curie，so I believe that the left hander is really smart as the Google says.
And the same golf series Left Hand Taylormade R11 Irons, Left Hand TaylorMade Burner SuperFast Rescue, even the Left Hand Callaway Diablo Edge fairway wood were clicked by the same customer in that store.

My purpose is to buy Left Hand Taylormade burner 2.0 Irons for my cousin online, but I do not know that I found the information about left hander; it’s pretty worthy this time. This is also the reason why my cousin is clever，so fantastic!!
