Picture an ice cream shop that offers only two flavors: vanilla (young people) and chocolate (elderly people). Over time, fewer young customers come in for vanilla while chocolate lovers keep coming back. Eventually, most of the customers will be enjoying their scoops of chocolate ice cream, representing an aging populace.
