I'm in Berlin now.
I go through the street everyday with thinking about the reason why they are tall.
The Girl is very tall!
Many girls are more than 170 cm.
10 years ago, I said to my friend "do you know why The European is very tall?" . He didn't know that.
I told a lie as joking him "you know the gravity is different from each area on the Earth, so European is talking the gravity less than Asian."
I haven't told my friend that it is joking yet.
But I start to think that It may be true...
