It was 15 years ago, when I was 25, my aunt Tossi turned 40. She and I went out to the bar to celebrate her birthday. One of her friends said to Tossi: "You are now on top of the hill!"
Tossi said, "I am not on top of the hill. I'm just getting started on the way up. When I turn 50, then I'll be on top of the hill. When I'm 60, then I'll be over the hill."
So now that I am the same age as Tossi was then, her wisdom is all the greater. Here your humble RT is just getting started up the hill. He is on the first step.
