“Answer the phone by Left ear”, I saw this quote spreading around social networking and emails. But this is another phone myth that “Left ear is good to answer calls”. And also they said that the distance to brain from LEFT ear (X) is greater than the distance to brain from RIGHT ear (Y) (X>Y), that why it is good to use the left ear. That is also a myth that there’s no any experiment shows that (X>Y), as we learned in high school science brain is in symmetric position in brain-pan. You can use your both ears to answer phones.
But it is a good thing that you interchange the ears when you’re in a long call. And also using handsfree is a good thing when you use mobile. But remember to use the branded mobile phone for own safe.
