FYI: If you want to read something sort of funny about getting older try reading the very last article in this month's issue of Field & Steam Magazine by Bill Heavey.
His column is called "A Sportman's Life", this month's feature (December 2018) is titled
"Coming of Age" -
Making The Most Of My Mature Years.
It is just one page of light reading, does not look like it's been posted in his online blog yet.
