I don't remember stating I had a degree in anything...as it happens I do, but I stated "Precision Engineer". I started making Steam Loco's with my father at the age of 10 and have been fulltime in Mechanical Engineering ever since and for the last 33 years had a Mechanical Engineering degree and am a Mmeber of the Institute for Mechanical Engineers.

I only made refence to my age and qualifications just to show that the B/S that would frighten a newbie into submission has little effect on me other than to raise a laugh.
