Here's a new study just published today. Perhaps you might have a look. This isn't the actual research paper, but a post explaining it in layman's terms. Maybe have a look at the poster's catalog and better understand the issue, because it's not just the adverse events you mention.

Edit: BTW I had a heart attack on Jan. 10, 2020. You are factually incorrect about my performance declining after that. I was back at work in one week after the surgery, and persistence hunted elk that fall.
