Hi,
I'm a retired teacher, on the "old Super scheme". I paid in a packet there.
I sometimes think about a friend of mine, a fellow engineer (my first life). He held a number of very senior jobs in Oz manufacturing, and usually worked at least 6 days.
He planned and invested and retired at 60, the ideal, or so it seemed. Soon he got the fidgets, and decided to do some casual hours in the industry. That grew and grew, and now he is back to 5 days!!
I never felt the slightest urge of that sort, being as lazy as they come.
Cheers
