Amortals live among us. In their teens and 20s, they may seem preternaturally experienced. In later life, they often look young and dress younger. They have kids early or late — sometimes very late — or not at all. Their emotional lives are as chaotic as their financial planning. The defining characteristic of amortality is to live in the same way, at the same pitch, doing and consuming much the same things, from late teens right up until death.
