Watched University Challenge with my dad last night for the first time in about 20 years.

Was pleased with myself for getting the maths questions right.

Then I remembered I am a professor of mathematics.

Took the shine off.

@kityates I remember many years ago just after I had graduated, reading a piece about how difficult VCRs were to program - never been a problem I thought - unless you have a electronics degree the article continued. Um yeah guilty there.
