It&#x27;s probably genetic; they&#x27;re not sure exactly what&#x27;s going on yet, but they know that stress exacerbates the problem. Most of the time, I&#x27;m perfectly fine, but if I get overly stressed, my heart doesn&#x27;t beat quite right.</p>\n<p>So, my cardiologist sent me to have some MRIs done to help him determine the most appropriate course of treatment. I&#x27;m scheduled to get those MRIs a week from today, and I just got a text about them, informing me that my cost for the MRIs is $350, which I have to prepay.</p>\n<p>I don&#x27;t know about you, but suddenly having a $350 bill due in less than a week is pretty stressful, which is not exactly good for my heart. It&#x27;s almost like the healthcare system in this country is designed to keep me unhealthy.</p>\n<p><a href=\"https://microwords.goodevilgenius.org/t/healthcare\" class=\"mention hashtag\" rel=\"tag\">#<span>Healthcare</span></a> <a href=\"https://microwords.goodevilgenius.org/t/healthinsurance\" class=\"mention hashtag\" rel=\"tag\">#<span>HealthInsurance</span></a></p>\n", "to": [ "https://www.w3.org/ns/activitystreams#Public" ], "cc": [ "https://microwords.goodevilgenius.org/followers" ], "published": "2025-06-23T14:35:36Z", "context": "https://microwords.goodevilgenius.org/contexts/83845c7e2caf4ef0a8e6becf9675dc14", "conversation": "https://microwords.goodevilgenius.org/contexts/83845c7e2caf4ef0a8e6becf9675dc14", "url": "https://microwords.goodevilgenius.org/o/10cd6bd77c0e45f8a1d0abe453ab16b7", "tag": [ { "href": "https://microwords.goodevilgenius.org/t/healthcare", "name": "#healthcare", "type": "Hashtag" }, { "href": "https://microwords.goodevilgenius.org/t/healthinsurance", "name": "#healthinsurance", "type": "Hashtag" } ], "summary": null, "inReplyTo": null, "sensitive": false, "attachment": [] }, "published": "2025-06-23T14:35:36Z", "type": "Create" }
