STUDY COMBINED WITH THE EXPERIENCE OF YEARS

Answer:
Wondering why have 6 "F"?
This is because our brain can't manage to proceed "OF"...amazing!!
If first time u can get 6 "F", it means u r GENIUS!
If ur answer is 3 "F", u r normal...
but..if ur answer is less than 3"F", then u need to see doctor lo... :p haha

想知道为什么吗？
我们的脑袋是没有辦法去处理 'OF' ，不可思议？
如果你第一次就算有六个 "F" 的话，你就是所谓的天才
如果你第一次只数了三个，属于正常，
至于连三个都不到的话，就建议你去看医生咯:p haha
