[Konidurase]

There are several key factors that make up the bulk an individual's identity. Some can be changed and adopted, others are not optional but just who you are.

Nationality, religion and political beliefs are the most obvious ones.

Gender/sexuality: pretty obvious.
Music taste: this is important as it often affects other areas such as fashion and perhaps even political persuasion.
Socio-economic status: which may be more important in some nations than others.
Age/generation: As always there is currently a gap between young and old, the 'digital natives' and those who try and switch the microwave on with a TV remote control.

What others are there?
