Elder people have a lot to say and some (not all) have a lot of wisdom. However I agree that whatever advice you take and follow, you will end up making mistake in other areas, so at the end of the day you have to live your own life, realise your own mistake and correct them.

Let's say it is interesting to hear their advice as they have more life experience. I would however not follow everything said as the context has probably changed, but I try to take out the useful information I could reuse
