How Coffee, Caffeine, and Bilingualism Boost Learning Power

You’ve probably heard that intelligence is fixed by childhood — that if you weren’t a straight-A student early on, your brain’s potential is set in stone. But new research from University College London challenges that belief, showing that IQ can rise or fall significantly during adolescence and may even remain flexible well into adulthood. What you eat, drink, or even speak could play a bigger role than you think.
