During the last fishing sojourn my fishing buddy Cikgu Aziz mentioned that, for us, there is no point of joining the paper chase because we are not looking for employment anymore; life is reaching phase 3 so "why bother." I tend to agree with that somewhat and answered "There's always lifelong learning for us to seek out." My buddy agreed.
Actually lifelong learning is available everywhere, it is only a matter of whether the learner is sensitive enough to learn from his surroundings. In most cases the normal man in the street is not aware of the things to learn from the surrounding, so the teacher becomes indispensable. It becomes a noble profession and students become enlightened because of the teacher.
