The non-metric rule of thumb [0] gives 490ft for 65mph; same ballpark. This incorporates reaction and actual braking, not just the latter. [0] https://en.m.wikipedia.org/wiki/Braking_distance

Regardless of what Wikipedia says, if you take almost 1/10 mile to stop at 65 MPH, either you or your car is doing something wrong.

Between perception and reaction time, you’re already at approximately 1.5 seconds. At 65 mph, that’s roughly 140 feet.

How does: > Either way, statistically, one of you will die this summer. go together with: > But you can take comfort in knowing that there were less than eight deaths per 10 million visits to national park sites between 2007 and 2018. ? I'm confused. How many people were there in that room when the ranger said statistically one of them would die? Were they for some reason more statistically likely to die than the oth…

The employees often work in the wilderness doing things like trail maintenance, and they're often young free-thinkers. Dropping acid and going swimming like the author recounts does not sound out of the ordinary.

They may be at slightly higher risk than the average family of four, and they rack up dozens of visits every season.

No, its “the occurrence of a rare event is an indication of the existence of the conditions in which that event occurs in that time and place, so if you have evidence that such an event has recently occurred, you should treat the place where it did as a place where that kind of event has an elevated likelihood of occurring”, which is far more specific and actionable than “better safe than sorry”.

This is a lovely example of HN pedanticism.

It's not pedantimums to complain that you're swapping in a completely different moral.

I worked the lowest paying job in a ski lodge one winter. One day while waiting in the cafeteria line, one hand on the stainless steel counter, I noticed that I got a bit of a shock from the steel railing on the other side. There was also a stainless fryer on the counter, but insulated with plastic legs, so I did some experimenting by completing the circuit a few ways: - Counter to rail: weak shock - Counter to fryer…

This sounds like the counter was picking up static electricity from somewhere. Touching it will shock you momentarily, but it's not dangerous.

Doesn't sound very likely. Static can come back, but it's not usually going to be constant enough to experiment with unless you're doing something to make it come back or there's a generator for it.

Usually it's good for one little light zap and then nothing for minutes/hours.

One time, I was driving at night in the Sierra after a storm - roads were covered in snow. It's a drive I've made close to 100 times without incident. Going around a bend, I saw a car in the ditch on the outside of the curve. I stopped the car, put on the hazards, and went to see if there was anyone in the car. As I was about to cross the highway a car come sliding around the bend more or less sideways. I stopped and…

Kind of related, but if someone is being shocked, live, what is the safest way to help them? The immediate answer might be turn of the circuit breaker, but what if we're in a giant office building? Or I don't have access or know where the circuit breaker is? Grab them with rubber gloves?

Kick them away (or sideways, basically anything to break their grip on the electrified thing they're locked onto) from whatever they're holding. Your shoes aren't conductive so you will be safe.

Alternatively, throw a scarf or other garment as a loop in between the victim and the source of the shock and use it to pull them away from it from behind them - the garment not being conductive means you'll be safe.

>It only takes 80ma across your heart to stop it In a lab, sure. In reality you need a lot of amps going into the body to get enough amps across the heart to screw with it. Defibrillators wouldn't be chock full of capacitors if that wasn't the case. Constantly repeating these sorts of misleading DARE-esque talking points is why nobody takes what the safety preachers have to say seriously. People find out through life…

Especially if the disrupting current got in through punctured skin (which the defibrillator is not allowed to do) > a couple amps from arm to arm This is very bad advice. A couple amps at 220VAC is devastating if actually delivered inside your body. The reason people routinely s…

But that's what a defib does. It disrupts your heart's rhythm. And then you hope it goes back to normal.

This reminds me of a time when I went to the grand canyon with some buddies. We stayed there for a few days. Then made the drive back to the airport to fly home Along the way to the airport some asshat setup traps along the highway. These were boulders the size of soccer balls scattered along the highway. We don't see these coming as there's a car in front of us Next thing you know that car in front is veering out of…

Was there no chance that the rocks were due to a rock slide, or was it out in the middle of nowhere such that it could only have either been put there or fallen off a truck?

There's a chance, I guess? And that's why you have a court system to settle these questions, instead of just locking people up.

I almost drowned on a beach without surveillance, jumping into the surf waist high, for fun, until suddenly the receding water pulled me just a few meters further away and now I couldn't touch the floor anymore, and was slowly being pulled further and further away from the beach. My girlfriend of the time was on the beach far enough away that she couldn't hear or grasp that I was struggling. By luck and after perhaps…

Drowning doesn't look like drowning. The thing they show in movies or on TV is not what happens so most people have no clue when someone is in trouble. In some cases kids drown in pools while parents are not only present but looking right at them. In others like yours people wave and smile from the beach as the person in the surf is about to die.

This interactive website lets you test your ability to spot drowning and develop a sense of what to watch out for - can you see which person in the wave pool is drowning before the lifeguard blows the whistle and jumps in?

The thing about nature is it is so beautiful and … suddenly powerful and overwhelming.

There’s no real good way to know if you’re prepared for falling into what is a crazy fast river or etc. It’s a pretty river one moment, and a death trap at the same time. Sometimes it’s just happenstance that you experience both.

Heat exhaustion once almost got me. It was shocking how fast your body can just turn off and you can just about feel organs just powering off and suddenly just standing up straight is like lifting the heaviest of weights.
