As I have said I am an engineer, I like to see credible evidence
and you have presented none.

When presented with a pint glass with about 10 Imperial fluid ounces in
it, an optimist will state that it's half full, and a pessimist will
claim that it's half empty. An engineer, however, will point out that the
glass is twice the size it needs to be.

Willshaw uses the term "engineer" to mean "mechanic".
