I applied for a job and got it, it wasnt what I originally set out to to do, I spent my time in college learning electronics and after being made redundant in my first job R&D for an electronic co I spent some time as a postman. I then started my first business which I dissolved before it went bang due to the depression in the 80's and took a job in a plastic factory. I saw a job advertised for security engineer and took it, I could back then find a fault at component level and repair PCBs but I couldnt now the components are much smaller. I used to fix TV's and stuff all the time, nobody ever does that nowadays its far more expensive to pay a man four a couple of hours compared to the price of a new one.
