Teaching may be an exception to the rule. When I retired from teaching three years ago I thought that was it, live off my super, spend time in the garden, hobbies, small trips etc. My wife works two days a week as she likes it so much
so I thought I would apply for casual teaching positions in my local area mainly to supplement our income, save for overseas trips and of course, buy more astro gear. I had no trouble in finding teaching positions, in fact I have taught at least six months in each year since retiring and will be teaching in term 1 this year at a local grammar school. While I still have good health and a positive attitude to work not to mention the social aspects, I will continue to teach even though it can be very challenging these days. I am now 61 by the way.
