Drive sense into an elderly man

hello picjim! i have learned through experience that the most hardheaded people are those who are aged or elderly, especially when it comes to their money and the way to handle it. I don't know if that comes with the territory, or with their thought they are correct since they have been there already for a long time and should know better than we do. I guess, if you can't let him see reason, then maybe you can find ways through media perhaps or other informative gadgets like magazines, to show him that his ways would not be the right way.. in dealing with financial matters. even with the truth glaring right before them, there are people who still don't believe unless they see someone of flesh and blood who had the same situation, to prove your point.
