If you’re an engineer and you’re reading this, you probably have experience with taking things apart or repairing them. I remember taking apart my prized toy train as a young boy. One time I even dismantled my father’s radio, only to get in trouble when my father found out. I was eventually put in charge of fixing gadgets around the house when they broke, which only caused my penchant for dismantling things to escalate even further. In my teens I was sometimes even asked to repair hi-tech devices like televisions, microwaves and VCRs, despite having no hope of success. All I remember is that I really enjoyed taking things apart. I loved the feeling of suspense when taking the cover off a device to find out what was inside. (Readers are warned that removing the cover of an appliance will generally void the warranty.)
