Well Steven (with respect to all those wonderful teachers who I think are great doing what they do) teachers never have left school and therefore somewhat insulated from some of lifes realities
.
But heck ex teachers always made the best sales people which I attribute to management of groups of children...management of buyer lists and listing prospects is very similar because you need to understand each individual and what makes them tick.
I employed ex teachers readily because they mostly were great performers in sales.
AND Steven your ability is very evident you always provide very well considered views
... just dont fall into the teachers trap of believing everything you read...particulary about dark matter
