That said, having an Apple watch is certainly much cooler than wearing those emergency call devices they currently sell for old people.
That's a problem, but I don't think that's the main takeaway from this story.
You could have a loving family and friends and still not be "missed for 3 days". 3 days are not big enough span of time for adults, in the grand scheme of things. E.g. if your wife is on vacation, or you/she work in another city, or have some deal going on, and you talk 1-2 times a week, it's easy for 2-3 days to slip by without anybody noticing you. Friends too might come by once a week or 1-2 times a month, and easily miss you for 3 days (that would already be more often than many people with close friends see them).
Heck, and even 1 day or even 2-3 hours would be enough for serious damage, if you weren't discovered after a fall/accident.
This is the coldest of cold takes.
A person falls, and nobody misses her or looks after her for three days. How is this not a problem of our current society?
You're not wrong, but it's also not unusual. Most people I know do not talk to their mom more than once every 3 days.
If I died today, the only place that could figure it in a day or so out would be my workplace. If I didn't work, then it could be a week before my parents or friends began to suspect something.
