Make your mind simpler, if you feel unpaid debts to 67 people, as some may passed away, some may still alive. Write thank you notes to these people to let them know how their kindnesses effected you and express your appreciation, do that when you are still capable, I don't think any of 67 would look for any financial gains, certainly if a few may need help, you could provide some assistances in your ability. Another way you could do to honor these people is to help others in needs, to let action of kindness go on and on.
