同学你好~
of becoming修饰the process作后置定语，与of losing并列
the process of losing vigour with time, of becoming more likely to die the older we get,
其中the older we get是状语从句，修饰becoming more likely to die
the process of losing vigour with time, of becoming more likely to die the older we get是主语
was something self-evident这部分是系表结构

祝同学学习进步~
