We all like to spice up our meals,
but, did you know that 129 teaspoons of pepper
all at once could kill you?
Perhaps, more concerning is that eating as little as a few teaspoons of nutmeg
就会诱发抽搐 心悸 恶心甚至致死
can induce convulsions, palpitations, nausea and possibly death.
Of course, sugar has also been linked to a myriad of diseases.
But, for a 150-pound person,
10.5 cups of surgar at once is deadly.
With that much sugar, you might alsodevelope some serious cavities.
But, don’t go eating toothpaste.
Fluoride is very safe in small doses and can help fight cavities.
But ingesting around 24 tubes with 170 millilitersor 6 ounces each could be fatal.
If you are trying to avoid wrinkles,
just know that 68 nanograms of botox is lethal.
It does stand for botulinum toxin after all.
Of course, injections use a tiny fraction of that amount ,
which prevents nerves from firing,
essentially paralyzing muscles.
And while you’ve always been told toeat your fruits and veggies,
enough oranges and you’d be overdosing on vitamin C.
Granted, you need to eat about 11,000all at once to reach this dosage.
809 vitamin supplements would do the same.
If healthy food makes you run the other way,
don’t go too fast.
Though our bodies can handle amazingly fast speeds,
we’re not so great at acceleration.
The earth is flying around the sun at around 1600 kilometers an hour,
and it doesn’t faze you.
But if it started accelerating to a faster speed,
we’d all feel the jolt.
14Gs of lateral accelerration,
and your organs would start to tear loose from one another.
Running fast will also warm you up,
But when internal temperatures exceed 40 degrees celsius,
heat stroke will kick In and could potentially lead to death.
Sweating can help cool you down,
But with any extreme heat, dehydration sets in,
causing decreased blood flow to vital organs like the kidneys and the brain.
As a result, they begin to shut off,
all the intestines break down and release harmful bacteria into your bloodstream.
当然 如果内体温下降太低 低于21摄氏度
Of course, cool your internal temperature down too much below 21 degrees celsius,
and your body enters a lethal phase of hypothermia,
which causes veins to constrict,
and blood flow to decrease,
focusing warmth on internal organs untill they begin to fail, too.
If you’re trying to see those internal organs,
try to avoid getting 7143 abdominal X-rays back to back,
which is enough cumulative radiation to kill you.
This ionizing radiation has enough energy to rip electrons from atoms.
5 grays of radiation is enough to kill 50% of the population
which a nuclear blast could administer.
If you’re hiding from a nuclear blast,
be careful of eating too many green potatoes in your bunker.
The green color that forms on the skin
is actually chlorophyll, which isn’t toxic,
but indicates the presence of the toxin solanine,
which is a defense mechanism against pests.
You might get sick from eating one,
but eat around 25 of these medium-sized green potatoes,
and your life could be on the line.
What’s good for our own survival in small doses can sometimes be lethal,
like potassium. Potassium ions are essential for nerve inpulses and muscle contractions.
But potassium chloride is also used for lethal injections.
You’d need to eat about 480 bananas to reach this lethal amount,
but your stomach might burst before you reach that.
Just remember the dose is the poison.
