USMC Commandant Gen Eric Smith was born 1964 or 1965 (age 58–59). Your comment makes me wonder if you have ever been in the military?
I am not concerned about the age of the commander. A 50-year-old suffering from a heart attack during exercise is uncommon, but it happens. It is difficult to make statistical conclusions from a sample size of one.
I am more concerned about the subordinate troops. Commanders are of very little use unless they have healthy and capable subordinates. Actual war fighting appears to require a lot of strenuous physical activity. I am skeptical that it can all be done sitting at a video game console.
If the forced mRNA treatment has made 20 to 40-year-old troops more susceptible to heart attacks when physically active, then we have a very big military problem indeed.
It is an easy question to ask, and fairly easy to prove or refute the idea with inexpensive health monitoring. The Military has all the data to answer such questions about their troops.
Has the rate of cardiac problems in Marine troops increased or changed in any significant way during the last three years?
The stricken Marine commander suggests that it is time to get a definitive answer to that question. And the answer makes a huge difference in military planning and strategies.
The politicians be damned.
