My favourite thing about neuroscience is discovering again and again how plastic the brain is. Anything can be learned and unlearned, at any age. A new skill, a different behaviour, a way of thinking - once you start, the brain will adapt.

"The soul becomes dyed with the color of its thoughts." - Marcus Aurelius 2,000 years later, as a neuroscientist, I can tell you he was right. Philosophy discovered what neuroscience proved: You're not stuck with the brain you have. You're building the brain you're becoming.
