Yeah it happens. Mt next door neighbor had a friend that died of a heart attack in his mid 30s.
Has happened a lot more often over the past 2 1/2 years.
My grandmother died of this exact thing. Her carotid burst and seconds later she was dead.
But she was not young, she was 100 years old.
My neighbor was 47, he had a heart attack while playing tennis. This person is 41. So like you said, it happens.
Nothing to do with covid shots. We're all genetic time bombs.
