I’m a professional theoretical physicist in my 40s and I never thought the day would come that I would realize I became shit at mental math. I can do quantum physics in my head but don’t ask me to add 17 to 34
I've also noticed that I drive more slowly/defensively, if only because I need more time to react to all these other bad drivers =P
You won't catch me (nor any of my brilliant brothers) doing math without a calculator... and I got a SAT790Math way-back-when (do they still score that way? I missed one question, only; many of my brothers scored 750+).
