18 Secrets That Professionals Know But You Don’t

If you work in a particular industry, you will know its facts. The rest of the people will find it as new information. 

A user asked the forum, “What fact is common knowledge to people who work in your field but almost unknown to the rest of the population?” Here are the common responses.

LIBRARIES

“Libraries throw away/recycle thousands of books routinely. A modestly sized library might eliminate a thousand books a month.”

COPPER, ALUMINUM, OR STEEL

“Virtually every piece of copper, aluminum, or steel you come across has been chopped to bits, refined, melted down, and used to make whatever object it’s a part of. Dozens, if not hundreds of times. Copper pipe probably started as hundreds of different wires from various devices worldwide at one point.”

PSYCHIATRIC PATIENTS

“Psychiatric patients aren’t a big money-generating portion of the medical field because wealthy people who give to charity for a specific medical condition they’ve had rarely want to admit to having been treated for a psychiatric condition. 

So, psychiatry gets some of the least attention from foundational grants and charity, fueling the homelessness crisis.”

PARKINSON’S DISEASE

“Parkinson’s disease is steeply on the rise. It’s the fastest-growing (by number of people affected) neurological disease, and we aren’t sure why. A lot of people think it’s related to microplastics. There isn’t a cure, but the drugs are okay. 

The only clinically significant way to ‘pause’ the progression of Parkinson’s and extend one’s life is high-intensity exercise. It’s been shown to halt the disease progression and keep symptoms in check, meaning it’s much easier to live with it than otherwise. Quality and quantity of life are higher when practicing regular high-intensity exercise.”

INTERNET

“Modern Internet is the biggest wonder made by human beings ever. It stretches across continents and is made by hundreds of thousands of people who make it work without ever seeing, meeting, or communicating with each other. It worked because we agreed on something common (protocols) to make it happen.

When you interact on the Internet, its ripples are felt globally at the speed of light. You go about your day without knowing you have put billions of electrons at work across space-time.”

EMERGENCY CALLS

“Most 911 calls an ambulance receives daily are not remotely close to being emergencies.”

ELEVATOR

“An elevator will go up to the top of the hoist instead of crashing to the floor in most catastrophic failures due to the counterweights.”

AIRPORT X-RAY MACHINES

“Airport x-ray machines automatically detect explosives hidden in baggage based on the material density. Hiding something inside an x-ray blocking material will cause it to get highlighted as something for a manual search.”

MILITARY-GRADE

DOCTORS

“There is no such thing as a perfectly functioning aircraft. Every plane you fly on has many maintenance issues, just not severe enough to affect flight safety.”

ENDOMETRIOSIS

“That Endometriosis is genetic. One of the primary causes of Endometriosis is the result of a mutation in the CFTR gene, the same genetic mutation that causes Cystic Fibrosis. I have a Career in Healthcare, and I suffer from Endometriosis.”

INSURANCE

“All insurance is a scam. It creates the need for its existence by driving up the cost of whatever it insures to a level that needs to be mitigated in the event of a loss.

A simple example, your surgery only costs 250,000 dollars because insurance exists. Knowing that an entity with deep pockets will pay the bill increases costs. If insurance didn’t exist, things would by necessity be much more affordable.”

MALE BEES CAN’T STING

“Male bees can’t sting (no stinger). They’re useless (the queen only needs one or two to mate with to keep the hive populated). They don’t even forage for pollen, etc. They do nothing but eat and wait for a very slim opportunity to mate with the queen. When temperatures drop in Autumn/Fall, the girls evict them from the hive, then die.”

TATOO

“Touching your fresh tattoo with your unwashed fingers is bad. It’s absurd how often we have to tell this to people.”

TRAINS

“Trains can be scary quiet. Most people hear them when they’re going 40-50 miles per hour, but in the train yard, sometimes you won’t hear a train coming up behind you until it’s a few feet away.”
