Almost 30 years ago, a young man and his associates bombed the Melbourne police headquarters, killing one policewoman and injuring 22 others.
He was 22, and was sentenced to life imprisonment (Australia does not have capital punishment), with a minimum of 30 years jail. He is currently suing the prison system for not allowing him to finish a course to be a counsellor - see
http://www.abc.net.au/news/2016-02-24/russell-st-bomber-takes-legal-action-to-complete-counselling-/7197390 - and as a result, his achievements over the past 30 years are in the media.
Of course, the whole article may not be correct about his achievements in the last 30 years. However, he has a lot at stake to tell the truth about his achievements since he is about to become eligible for parole. If we believe it, he has changed from someone who couldn't read or write, to someone who has a PhD, and has achieved a number of other things. If he hadn't been imprisoned I can't imagine that he could have achieved any of that partly because he would have needed to work or to continue to be a criminal.
Imagine what any one of us could achieve in 30 years of retirement ourselves - given what he may have achieved from such a low starting point. We all have many advantages that he doesn't - the first being freedom.
