The age where I peaked, like Alter Ego said before me.
It's gotten to the point where I obsessively look for the technology, fashion, and pop culture in vogue at the time. I collect pieces of the subculture of that age like fanzines, supermarket flyers, or the headlines of certain significative days.
That, and I'm writing a dream-fulfillment piece where I start again in that time, without the hindrances and drawbacks I had since birth.
Other than that... I have a serious reading problem.
