I've only really had three hair styles in my whole life:

1. standard boyish fringe + scissored cut round back and sides: up until about aged 16/17
2. standard-issue indie mop - up until age 20
3. grade 4 back and sides + short/choppy/spiky on top: aged 20 onwards.

I'm 30 this year - this current hair style is reaching its 10th anniversary. Is this fairly normal? I don't know whether i'll get round to changing it until I am forced to by baldness (my hairline has remained fairly resolute to date).
