Why do people fall for this?

[Aparecium]

The latest viral spam that is being posted all over the place on my SM groups, mostly by educated, intelligent people. And then reposted by others. Why do people fall for this? Do they really think this is how cardiologists spread important health messages? Doesn't that last sentence appear dodgy, with its capitalisation and the rogue apostrophe?

I don’t understand.
Is there some other information attached? Or do people think they are preventing heart attacks by posting a message on SM?

I think it’s just poorly worded: I don’t think it’s intended to imply that cardiologists have actively put this message out to be shared virally, but that cardiologists would endorse more people being told about e.g. the unusual early signs of heart disease that few people realise are early signs because it could help save lives.

Nobody with two brain cells to rub together would repost any of this stuff. It’s pretty much the chain letters of my teens transposed to the SM world.

It's some long-winded nonsense claiming that, if you have heart-attack symptoms and you're on your own, you can keep yourself alive by coughing constantly while you drive yourself to hospital. I'm not going to post the whole thing.

I've received it five times in the past 24h. Two of which were followed up by "Oops, sorry, BHF says it's urban myth."
