14 years in toolmaking taught me one thing, there are four levels to making things,
Fool proof, readily achievable,
Child proof, hard but not impossible,
Idiot proof, almost impossible but not quite, and with a high risk of striking a nerve or two,
Squadie proof, impossible.
Please don't get me wrong, I have a great respect for our service men and women, current and past, and I thank them all for their sacrifices, dad is a Normandy veteran for a start, but please, I have seen things done to the product I used to help make that defy belief!
