late-night swim

Running in the morning, swimming in the evening and in between eating lots of chocolate.........
My small brothers 12th birthday today! He got a PSP and would like to play and chat about that with people in china but he forgot he can`t speak chinese ;)
Is it normal nowadays that a 12 years old has already a three years relationship with a girl that`s two years older?
I`m a bit afraid of getting really old................
