The author became aware that there are hundreds of retired teachers in the community who want to continue to learn, or at least to have their intellect stimulated. Some join clubs or read books or do crosswords or even surf the net when they retire, but these folks wanted to be stimulated with some mathematics. The author was initially surprised that any group of people let alone retired teachers actually wanted someone to talk to them from that subject about which most people boast of their ignorance (even abhorrence). After completing a series of sessions that talk about an aspect of mathematics to fellow retirees at the College for Seniors, the author realised that adult learners and retired ones are more than willing to continue to learn mathematics for its own sake as a source of intellectual stimulation. He points out that retiring from teaching is not the end of a meaningful engagement with mathematics.
