I got a smartwatch early in the pandemic because time stopped having any meaning and I started missing meetings all the time because I'd go do something not at my desk and then forget I had a meeting until I was super late. Also I had to set up reminders to do normal shit (eat lunch, walk dog, feed dog) because otherwise I'd forget. I tried doing it with reminders on my phone but then I'd set my phone down five feet away and forget.

Basically I have a smartwatch because my brain is broken and I need an electronic device strapped to me to nag me to behave like a human being. :(
