My IQ = 128, when I was @14.
I’m no genius. Most engineers are in that ballpark.
As for languages, I’ve no special skill. I was brought up speaking Spanish, English, and Tagalog, and I am fluent in them solely through circumstances. I have since learned French, well enough to read it effectively (I can read the newspapers, Dumas, Zola, etc., but dont make me do poetry). But I have severe problems with French conversation, no ear for it. With Spanish and French I can make a fair go at reading Italian and on a good day Portuguese. I had a couple of years of Latin. Very little has stuck, my daughter is way better at it. I am learning Basque now. Its going very slowly.
I didn’t say you were a genius. I just said that someone who is an engineer and speaks multiple languages shouldn’t have his IQ called into question.
