I think we should be careful about saying that sort of thing. Strokes did happen to some otherwise healthy people at that age, it was just rare. The rate of strokes in younger people has been growing at least since the 90s. What would be really helpful knowledge would be to find out what the statistics are on the rate of strokes in otherwise healthy people under 60 over a really long time and see if there's an uptick around 2020. I'd bet anything that there is. The question I'd have is how big the difference is between pre and post 2020.
Edit: Sure enough.
One study published in JAMA in April 2021 found that the risk of stroke was more than twice as high for COVID-19 patients when compared to people of the same age, sex, and ethnicity in the general population—82.6 cases per 100,000 people compared to 38.2 cases for those without a COVID-19 diagnosis.
In another Swedish study published in the August 14, 2021 issue of The Lancet, researchers found that within a week of a COVID-19 diagnosis, a person’s risk of heart attack was three to eight times higher than normal, and their risk of stroke was three to six times higher. The study revealed these risks remained high for at least a month. The average age of people in the study was only 48 years.

As information about COVID-19 has unfolded since the first cases were seen in the U.S., doctors in New York City have been noticing a troubling trend. Some young people who were mildly ill or had no noticeable coronavirus symptoms developed blood clots – and experienced strokes when those clots blocked blood vessels in the brain.

I remember someone (probably here) saying that the Shadow of Mordor/War "Nemesis System" could have become a widespread gaming system similar to how the unique mechanics of Dark Souls games became an entire genre and now there are all kinds of games that use the system and tinker with variations on it to great effect now called "soulslike." But because WB or Ubisoft or whoever made a show of patenting the system (and apparently won actual lawsuit challenges to it?) there is no genre of "shadowlike" or "nemesislike" games. That it was a clear example of a patent actually depriving us of an entire potential genre of games.
edit: I swear I read this whole thread before commenting but I missed EllenKelly already mentioned it. And yes, it has been discussed around here.
