Lately I've been pondering this question in my own experience of learning to paint better. They say as we age our brains become less elastic, whatever that means. (sounds ominous) But they also say keeping it challenged with new learning can stimulate neuron growth and new synapses. For me it feels like half the battle is to put a halt on old patterns and habits of doing things and intentionally working on the newly learned information. But is intention enough?
