This sort of thing can really happen. Heart attacks can be caused by increased cardiovascular activity, and if you do it right, sex can really increase cardiovascular activity! In my case, this happened twice. The first time, in 2008, I collapsed but blew it off and my wife didn’t push me to go to the hospital until the next day. On the TV shows the paramedics run an EKG and go, “Aha! Heart attack!” Yes, that can happen, but in a lot of cases, by the time they get there the event is over. At that point, the doctors do bloodwork and test for various trace chemicals given off by the heart under stress. If the chemicals are there, but the EKG looks good, it means you had a heart attack in the last 6-12 hours. However, if you delay going to the hospital, the chemicals dissipate and flush from your system.
After my second heart attack, in 2016, my wife made me call the emergency squad immediately. The EKG was clean, but the bloodwork showed I had a problem, so I ended up in the cath lab later that day. That’s the gold standard, and they discovered 70% blockage in the ‘widowmaker’. I ended up with a stent and the ability to continue giving my wife grief with my persistent existence.
Lots of readers laughed about the antics of Riley and Seamus and wondered why Riley Fox’s namesake wasn’t the worse of the two. Trust me, all three-year-olds are pains in the tail, no matter their sex or who they’re named after! I’ve had three children and five grandchildren. I know about three-year-olds! As for the line, “Oh no! It’s Tio Grim! Run for your lives!”, my son’s girls (11, 8, & 5 at the time) pulled that on me once when they stayed with us.
