Five Years Since Surgery

Wow!  It's been five years since I started this blog.  That was a few months after surgery, which occurrred, if I remember correctly,  on the day of the winter solstice.   One of my posts showed a survival  (survivorship ) curve which flattened out after five years.  The slope  (loss rate) likely approaches that of the general population (with some age adjustments).   This area of statistics is called survival analysis .   Survivorship curves come in several shapes. Here are some examples for different times and countries.  The mid-life slope for Europe is about 0.5% per year.
