oldster 

A person who has transitioned from adulthood into Olderhood . Part of the “Now Generation” oldsters have a desire to live life to the fullest, travel, meet new people, exercise, eat healthy, and incorporate a little bit of silliness in their lives. If youngsters have youth and dreams, then oldsters have age and wisdom. In this age of information, oldsters live in defiance of their advancing years and continue to crave new ideas and experiences, and have an insatiable thirst for learning.

In a classic oldster move, my neighbour decided to learn Spanish at the age of seventy.
