I just now noticed that 41 (years) times 365 (days in a year) = 14,965 (days). This means that in less than a month I could be at my 15,000th day. For some reason this feels momentous. 15,000 days! That's huge!
I vaguely remember this concept of counting your age in days, and after rummaging around in my brain, I found a link: "Metric Birthday" (Kelvin Hartnall). According to this link, my 15K "birthday" will be May 1, this year. I wonder if I can get my wife to make me another cake?
