What I have learned from old people is that they are the most experienced people in the world yet they act so cool about it. They are always sitting quietly on their chair just observing you. They have seen a lot in this life so much experience, if only we could relate with them better one won't fall into mistakes as these old ones have fallen into several mistakes during their life time and have "obviously" learned from each of them. The old ones can really help the young ones in life with their life experience.
