About Me
I used to be a computer programmer and service engineer, but then I re-trained as a science teacher.

I recently retired from teaching chemistry at A large school in Sheffield.
(In England, if you are connecting from foreign parts)

My hobbies are writing programs, making and listening to music, making electronic circuits, marking exams and mending furniture.  Also taking care of my house and family.
