There’s a quote attributed to the Portuguese writer, Saramego, that says, “old age starts where curiosity ends”.

When we’re young, we’re ‘naturally’ curious. We’re willing to try new things, take new paths and push ourselves (often to the point of discomfort). When we’re old, according to conventional wisdom, we seek comfort and contentment. We seek safety, and are willing to trade excitement - indeed, believe we’re required to trade it - in return.
