How Smart Is Your Right Foot?

[2011.10.05] 一封網路郵件，「How Smart Is Your Right Foot?」，是一則廣為流傳的訊息，但這是真的，細節參見：「How Smart Is Your Right Foot?」《Museum of Hoaxes》(2005)。

大致為：右腳順時針轉，畫圓，再用右手寫6，即逆時針轉，這時右腳會不由自主地跟著右手。

仍有人回應說他可以outsmart 他的右腳；

有一則回應說，他可以右手/腳逆行，但他是個左撇子，左手/腳則不行了~~

It's a bit like the old "pat your head while rubbing the stomach" trick.

[結論]：人們對於左右的理解與實際行為是完全依印象，並不細思其理由與手腳的功用。那麼更遑論是否左右腦有關。看完這則，我還是不瞭解大腦(或是其他部位)對於肢體的控制。
