Ever too old to learn?

I think that we can learn a lot from people that are more experienced than we are. People like our teachers and parents are there to guide us in a general direction of how to live life properly when you are out on your own. People tend to develop a closed mind as they grow older, but in reality there is always a possibility to learn. We should always have an open mind to new lessons we have to learn. However, it's necessary to filter the information to make sure that you are indeed learning the information you want to know about.
