I really do not think that your friend's creditors will be prepared to write off their debts when she retires, and certainly would not advise her to rely on that with regard to her future financial planning.
An unsecured creditor can quickly change to become a secured creditor by taking a Charging Order over her property. These are becoming more and more common, and can result in possessory action being taken in the event that the debt remains unpaid.
I think that your friend ought to do something proactive now to deal with her creditors, rather than wait for problems to come to her in the future.
