healthy people don't just drop dead for no reason
This is ignorant and quite upsetting for anyone who has experienced a close one's sudden death.
There is such a thing as SADS (sudden adult death syndrome) which is name the name given to deaths in young adults that aren't explained in the autopsy.
I think there have been a couple of high profile cases involving footballers.
Pathology isn't an exact science. Quite often there can be ambiguity about cause of death.
In another few years we will all be having genetic testing to check if we have a predisposition to a variety of illnesses/diseases. We already see this in done fields if medicine.
In the near future this may mean that people have more of an idea of their vulnerability to things like heart attacks, strokes, different types of cancer, diabetes, etc.
So maybe sudden deaths in middle age won't be such a surprise.
I've known quite a few people who have died 'young' (40s - early 70s) recently. One was lung cancer/ex heavy smoker so not a surprise but the others were, sudden heart failure and rare, untreatable cancer.
On the other hand I know a man who lasted into his 90s and died in an accident, seemingly resistant to the effects of obesity and alcoholism!
Most of us will die because of the lifestyle choices we make. Smoking, diet, sedentary life, stress, alcohol, etc so most of our deaths really shouldn't be a surprise.
