It would appear from most "posters" that the the average "Jack" now serves till pension.Times have changed dramatically since I joined. In 1963 when as a junior, committed to 9y + 3y, the ony way out being dischaged as unsuitable/medical or by purchase. We counted the day till discharge and only a minority signed on for the next 5y. I personally bought my freedom after 9 y ( 6y mans time) for the sum of Â£ 100 in 1972 ( how much is that in todays money?). I enjoyed my time in the mob but 15 year old was far too young to sign away my youth.
