Some of those doctors died while exercising. Exercise is generally good for health but no guarantees either.
James Fixx the running guru died while running many decades ago. That stuff happens.
Exercise is still generally considered a good thing.
The real open question is: does the vaxx do something to our circulatory system that makes exercising dangerous? There seem to be a lot of young athletes dropping dead. And doctors dropping dead while running or swimming.
Is the problem exercise?
Or is the problem the vaxx?
Or is this all an illusion and is there really just nothing going on at all? Ask the insurance companies and morticians.
