Some people like to live dangerously. They seek out adrenaline in everyday life and through extreme sports. Others prefer to stay safe and, preferably, on the ground. A study conducted in Britain found that 6 in 10 people think of themselves as 'risk-averse.' 69% of the respondents say they're afraid of the consequences those risks might have.
We all probably try to steer away from the things we know are dangerous. But how many unknown dangers are lurking around us? One Internet user was probably wondering the same when they decided to ask: "What's something most people don't realise will [unalive] you in seconds?"
People love morbid stuff on the Internet, so the thread quickly climbed to the top of Reddit's trending content and garnered over 16,000 replies. If you're prone to anxiety over your health, read at your own risk, Pandas!

I would venture to say most people realize what can kill you instantly but less commonly discussed would be dehydration.
Yes you can die within seconds from it.
Heart failure is what gets you and if you are already primed for a heart attack due to either unhealthy habits or genetics, dehydration can kill you in seconds. Some drop dead of a widow maker right there on the spot.
Dehydration truly is a gamble so be cautious with it. Happens a lot in the summer months as people pick up alcohol and energy drinks instead of electrolytes. .

Those green transformer boxes found in people's yards. I've seen so many people sitting on them, climbing them, standing on them, playing on them. Those things transport thousands of volts of electricity and it only takes one second to receive the electric chair treatment.

A ruptured aneurysm can kill you in seconds. It's often sudden and without warning, making it extremely dangerous and usually fatal if not treated immediately.

Anyone who works in a shop (hopefully) knows this… but compressed air. Not an uncommon thing for you to use it to blow metal shavings or other debris off your clothes after you’re done working, but if you have even a small cut somewhere and you get the air gun too close you can put an air bubble in your blood stream which will kill you the moment it passes through your heart. From what I’ve been told it is very painful and only takes a few seconds.

Using a massage gun on your neck...
>*While handheld massage guns are generally safe to use on muscles, using them on the neck can be dangerous. The high vibrations produced by massage guns can injure unprotected areas of the neck, and in rare cases, can cause soft tissue damage or stroke-like symptoms.*.

Eating polar bear liver. You’ll die of vitamin A poisoning. Vitamin A is not water soluble and eating too much can lead to painful symptoms and death. One polar bear liver has enough to kill over 50 adults.

If you get hit in the chest at a specific part of the heart's cardiac rhythm, dead. If you accidentally massage your carotid and have a vagal sensitivity, dead. If you have a genetic predisposition for certain arrhythmias and get startled, dead. The heart is a tricksy thing
Eta this is very rare. However, if you have any family members who have died unexpectedly and young and have a history of fainting for no reason get an EKG asap. .
