Isn't one of the early conclusions of the "evidence based medicine" movement that this is not in fact true?

At age ~35 I had a pretty comprehensive medical checkup as part of my Australian permanent residency application.

I asked the doctor if I should be getting checked like this regularly.

“Do you feel okay?”, he asked. I said yep. “Then no”, he said.

Sure, but what does that have to do with the linked post?

(1) That the narrative of Apple Watch saves lives is a totally false premise.

(2) That if you don't see that's the premise, you're being naive. Why would otherwise anyone care about some Redditor's doctor visit?

(3) That the underlying public health issue isn't the lack of Apple Watches.

The overwhelming consensus is that men don't see out health help as much as women do. Peruse through this (https://scholar.google.com/scholar?q=related:y2_y94H6XCwJ:sc...) if you're not persuaded.

It's not worth speculating if Watches and other gizmos make men go to the doctor more often or whatever. This is not the first nor the last gizmo. Blah blah blah, some benefit, but not a huge one. Otherwise some other gizmo would have long ago radically improved men's health, but the difference in mortality between men and women and men's fewer encounters with medicine persists since decades ago.

If every otherwise healthy man went to their doctor for a checkup today, how many would have their Afib detected? EKGs are not routinely given during checkups, and Afib is not necessarily constant enough that a doctor will catch it during those few moments he has the stethoscope on your chest. And even if it is happening he may not pick up on it.

Afib is relatively common (2% to 9% depending on age), and so is outwardly healthy people dropping dead with no prior warning. The premise that a 24x7 Afib detector on your wrist will save lives is quite plausible.

Now, what you may get from this post is that you should get an EKG once in a while, and not buy an Apple Watch or other gizmo for that purpose, but to suggest that merely visiting the doctor will achieve a similar result is obviously incorrect.

Just because two things are "common" does not mean they are related. Afib is way, way down on the list of things causing outwardly healthy people to drop dead.
