Interesting really.
You know I have been tracking my 100m sprint times over the last 25 years, and it seems that now in my late 40's, I am running faster and faster each year. Of course I need to seasonally adjust the numbers and apply some statistical homogenizing and I only guarantee accuracy to within a few seconds, but still, I just keep getting faster. I truly amaze myself ....
