Why Are CVS Receipts So Incredibly Long?

If you’ve ever conducted business at one of the nearly 10,000 CVS Pharmacy locations in the United States and count yourself among one of the estimated 62 million members of the store's ExtraCare discount incentive program, you’ve probably been handed a receipt that is more scroll than slip. These transactional documents, which have been known to literally be several feet of thermal paper long and full of merchandise coupons, are often wadded or folded up like a bath towel and handed off to the consumer.

Is this an environmentally mindful practice? And do these coupons really keep people coming back for more?

CVS has stated that the lengthy receipts are intended to demonstrate the value of being an ExtraCare member by offering ExtraCare Rewards, typically a dollar or percentage amount off of a single item or purchase. Some of the receipt's oversized real estate is also taken up by a solicitation to participate in a satisfaction survey. (Though it’s not likely that one of the questions is about the length of the receipt.)

Simply put, the chain wants to vividly illustrate the benefits of being an ExtraCare member, which also helps the company by allowing them to track your purchase history. The idea is that the Russian novel-length receipt will excite consumers who feel as though a surplus of savings are being delivered right into their hands.

The problem is that the coupons are often quick to expire or can sometimes exclude sale items, registering disappointment when a returning customer presents a slip for $2 off a bar of soap.

You can, of course, opt out of receiving a paper receipt through your ExtraCare account online or via the app, though the process requires a few steps to complete. The coupons will then be sent digitally via your smartphone. Since introducing that paperless option in 2016, the company claims it has saved 3 billion inches of paper that would otherwise have been squeezed into a ball and stuffed into your glove compartment.

Alternately, you can always use it to replace a broken window blind.

Which brings us to the other and possibly most important motivation for those long receipts: Social media engagement. The more people express dismay at those long receipts, the more exposure CVS receives. Considering their 2018 merger with health insurance giant Aetna cost more than $70 billion, some free publicity could come in handy.

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.
