When do we get old

I was raised at a small SW Ga town, HS class was 66 total kids in class of 1966. I lost most of my best friends, and they did not make it to 59 even.
I came along when my parents were in early to mid 40's, and an only child, they passed decades ago. There is a site on FB where all the kids from that town of classes of 50 and 60's are kept up with. Half of us have already passed. Close friend passed just last Tue.
We all know life is limited. The older we get, the more we realize it. Everyone just needs to make the most of or time on this Earth. We know that, just need a reminder some times!!
