It's a woman thing. Each plateau a woman reaches, has a label. 20s- hot chick, 30s- trying to stay hot chick that looks good for having 4 kids. 40s- the dreaded"Cougar". 50s- Should have seen her when she was 20. (hot chick).
After that, it all changes. 60s.- I'll be a great grandmother soon. 70s- I'll be 80 soon. 80 and up- Can't believe I made it this long and I really can't remember how old I am.
So I guess 60 is the magic number when getting older is a thing to be proud of. Or, bigger than that, It's when you finally accept the fact that aging is part of the process of life that you can't do anything about. So, a thing you are ashamed of turns into something you are proud of. I think there could be a lesson there that if applied to many areas of our life, things would be a lot easier.
