I agree completely. My aunt, well my great aunt actually, is 93. She is literally more active than me! She goes bowling, still, drives, volunteers, goes to church, and visits family and friends often. She is still very with it mentally, but I will admit after 90 she has declined mentally a bit.

My point is, this woman has touched a lot of people's lives within her 'old' age. She helped my family out a lot at one point. She's spent decades volunteering. She's been there for a lot of people and IMO helped to make the world a slightly better place in her own way.

It's never too late.
