Why don't paramedics run to emergency patients?

Ross Cohen:

I’m glad you asked, because I promise you it’s not due to a lack of concern. It’s actually perfectly logical when you see it from our point of view …

3 MAIN REASONS

  1. Running is risky. If we trip, fall, [and] get hurt—now there’s two patients.
  2. Running to a patient prevents us from spotting hazards on the way in. Remember, we’re walking into an unknown. We must carefully observe and assess for danger. On the walk in, we’ll notice the downed power lines, the room full of people passed out from a gas leak, the dog protecting its injured owner, the hoarder’s junk on the floor when we round the corner, the attacker who assaulted the victim, the weapon lying next to the bystander, etc.
  3. Running makes it harder to keep our cool and operate at peak effectiveness. We need to be the calmest person in the room. Everyone takes their cues from us. We need to think clearly and act deliberately, decisively, expeditiously, [and] smoothly. It’s hard to do that if your own heart is beating out of your chest, you’re breathing heavily, and visibly excited. It takes mental discipline to restrain our own excitement and concern to work professionally and unemotionally in scary situations and adding significant physical exertion to an already stressful situation is not helpful.

5 LESSER REASONS

  1. If the patient sees us running toward them, they may become even more distressed. Our demeanor can be either a calming or aggravating influence.
  2. We’re carrying equipment: stretchers, chairs, oversized bags, expensive EKG monitors, etc. Some of these things we can barely walk with, let alone run.
  3. It doesn’t actually save much time. If we parked far away, which is rare, we’ll be quite out of breath running a long distance with our equipment and have that much more opportunity to get hurt. If we parked close by as we usually do, we might shave at most a few seconds off our arrival time, which would not matter in 99.99 percent of cases.
  4. If you run on every call of every shift, across every street, down every driveway, up every flight of stairs, through every hallway … it’s just a matter of time before you twist an ankle, bang a knee, split a lip, fall down stairs, etc. I’ve known many EMTs who have gotten hurt and/or split their pants or something and that’s without running. We’re not professional athletes in tip top shape; injuries happen enough as it is and running would only add to it.
  5. We work on highways and highrises. We work in backyards and backwoods. We’re in people’s messy bedrooms and cramped basements. We climb stairwells and traverse steep inclines. We work in the rain, the heat, the cold, and everything in between. Running just makes all these things harder.

Those are some of the reasons we don’t run. The only real reason to run is that people would stop assuming a lack of urgency/concern when we merely walk briskly toward them. Trust us, it’s way better for all involved if we avoid running.

Why Are Sloths So Slow?

When it comes to physical activity, few animals have as maligned a reputation as the sloth. The six sloth species, which call Brazil and Panama home, move with no urgency, having seemingly adapted to an existence that allows for a life lived in slow motion. But what makes sloths so sedate? And what horrible, poop-related price must they pay in order to maintain life in the slow lane?

According to HowStuffWorks, the sloth’s limited movements are primarily the result of their diet. Residing mainly in the canopy vines of Central and South American forests, sloths dine out on leaves, fruits, and buds. With virtually no fat or protein, sloths conserve energy by taking a leisurely approach to life. On average, a sloth will climb or travel roughly 125 feet per day. On land, it takes them roughly one minute to move just one foot.

A sloth’s digestive system matches their locomotion. After munching leaves using their lips—they have no incisors—it can take up to a month for their meals to be fully digested. And a sloth's metabolic rate is 40 to 45 percent slower than most mammals' to help compensate for their low caloric intake. With so little fuel to burn, a sloth makes the most of it.

Deliberate movement shouldn’t be confused for weakness, however. Sloths can hang from branches for hours, showing off some impressive stamina. And because they spend most of their time high up in trees, they have no need for rapid movement to evade predators.

There is, however, one major downside to the sloth's leisurely lifestyle. Owing to their meager diet, they typically only have to poop once per week. Like going in a public bathroom, this can be a stressful event, as it means going to the ground and risking detection by predators—which puts their lives on the line. Worse, that slow bowel motility means they’re trying to push out nearly one-third of their body weight in feces at a time. It's something to consider the next time you feel envious of their chill lifestyle.

Are Any of the Scientific Instruments Left on the Moon By the Apollo Astronauts Still Functional?

C Stuart Hardwick:

The retroreflectors left as part of the Apollo Lunar Ranging Experiment are still fully functional, though their reflective efficiency has diminished over the years.

This deterioration is actually now delivering valuable data. The deterioration has multiple causes including micrometeorite impacts and dust deposition on the reflector surface, and chemical degradation of the mirror surface on the underside—among other things.

As technology has advanced, ground station sensitivity has been repeatedly upgraded faster than the reflectors have deteriorated. As a result, measurements have gotten better, not worse, and measurements of the degradation itself have, among other things, lent support to the idea that static electric charge gives the moon an ephemeral periodic near-surface pseudo-atmosphere of electrically levitating dust.

No other Apollo experiments on the moon remain functional. All the missions except the first included experiment packages powered by radiothermoelectric generators (RTGs), which operated until they were ordered to shut down on September 30, 1977. This was done to save money, but also because by then the RTGs could no longer power the transmitters or any instruments, and the control room used to maintain contact was needed for other purposes.

Because of fears that some problem might force Apollo 11 to abort back to orbit soon after landing, Apollo 11 deployed a simplified experiment package including a solar-powered seismometer which failed after 21 days.
