The key to being a successful sniper has more to do with the intended target remaining stationary for a few seconds than it has to do with being a superior marksman.

Butler proved that.

Engineers don’t use much more than basic math. All the 3D calculus, algebra, trigonometry, etc. I had to take y on get my degree I never use.

Interesting.
What fields.

I wonder if that's a function of computers in the workplace?
My father was an aeronautical engineer dating back to sliderule days. I've seen some of his work on propulsion and orbital trajectories. I can do a little math, but this stuff might as well have been hieroglyphics.

Your doctor/hospital drives up costs much more than we do. Your doctor will happily bill you more than the contract allows if he can get away with it.

That is either an outrageously ignorant statement, or a bald-faced lie.
I kind of hope, for your sake, it is the latter.

I could write a tome in response.

E.g., the number of times insurance tried to deny coverage for critical tests/procedures just to "test the waters." I had to take the time to get the insurance medical consultant/physician consultant/clinical reviewer on the phone. I'd get their name. I would tell them I was recording it, along with their medical advice, qualifications, and opinion in the patient record. Lo and behold, after pleading they were not providing medical advise, they would inevitably realize they were cooked, and consent to coverage. 100% of the time. Absurd!

Our billing dept would send a pre-negotiated bill to a patient's company for reimbursement. The insurance company would respond a check for some fraction of the bill. The billing dept would contact them re: the discrepancy. The insurance point of contact was inevitably a new hire, pleading confusion or ignorance. After several f/u's, the company would say "Whoops, you're right. Our 'bad.' We'll send the balance due." The next check arrived at some fraction of the balance. Rinse and repeat, often x 3 or 4.

Patients are oblivious.
They are blind to the process.
After all, they pay their premium, and assume (often incorrectly) insurance is paying fairly for their care.

Medicare compensation is far lower than private insurance. But credit where credit is due, medicare pays what is owed, on time, as promised.

Just about everything you touch in a day contains an adhesive.
Phone, shoes, mattress, auto, plane, furniture, books, beer bottle, packaging, envelopes, tv remote, appliances, sporting goods.

They are boring but they pay the bills.

Construction (Commercial bldgs):

Holding a lighter under a sprinkler head will NOT set off every sprinkler head in the building and cause a distraction so you can escape. It will only set off the sprinkler head directly above it and you will get covered with water and green thread cutting oil that smells like hell. You WILL, however, at least cause a distraction as the alarm goes off and everything near that sprinkler head gets ruined.

I wonder how much computerized simulation and analysis tools do in areas which previously required those upper end math skills .... or .... if, given computers' capacity, the curriculum should be altered.

You sill have to be able to understand the output to ensure that you're getting the expected result from the input.

Depends on field and size of company. I’ve used calculus working on several projects. The larger benefit of higher order math, understanding concepts and applying to critical thinking to address an issue.

International banking. I work hard so that we use your seed money wisely but I fight a losing battle. People are never frugal with other people’s money.
