You know what I mean:

'25 year old mother of one Tracy..'
'18 year old unemployed Andrew..'
'42 year old lawyer Thomas..'

The age and very brief description used to conjour up your lifestyle before detailing what crime you witnessed, what you stole from Comet, the chickens toenail you found in your Greggs pastie, the court case involving mars bar induced rage etc

What would yours be?
