And pray tell, how will you make money selling these devices? Surely the investors will want a return? The moment you sell them, you'll have the full force of the audiologist's association in your area against you, and they'll have the weight of the government to enforce it. Or they'll force you to sell them at the same price as all the others.... And now you're back to square 0.

Um, the local "professional association" whose mandate is to "protect the public" from low prices?

Well, look (ha!) no further than the egregious monopoly exerted by Luxottica and the equally corrupt professional associations in your jurisdiction making sure that the prices stay high.

Beats me, but I always use a scrap of wood to push or guide my workpiece.

Anything to bring down the scandalously high prices of some of these medical gizmos. Next, glasses. Hearing aids.

Sochi were the most expensive games in history. I was just amazed at the pitiful quality of the materials.

Really? That's fascinating. Does cardboard usually look like sawdust too like the doors in my place? And where did all the money go?

Yeah no kidding, did you see that athlete that was locked in a bathroom and punched his way out the door? The door was basically cardboard.

In Montreal we had the VIP parking sticker fiasco. The roads here are too cracked and broken for anyone to speed on them, so instead, we had special stickers so people could park for free.

Yes, but they're also quite deaf. They seem oblivious to the vacuum cleaner. I've seen some fat, stupid fruit flies resting on my kitchen counter that *stay put* as their wings start to bend from the suction... Then, womp! down the hose and that's that.

I assume it's far easier to drop the samples into a horizontal tube with an open hatch. You just let gravity magically suck the sample into the hatch. I guess a rocket erector is less failure-prone than some sort of telescopic arm to put samples into an upright rocket. Also, the hatch door will close by itself when the return rocket is horizontal. One less mechanism to worry about, or at least simplify.

As for the return, I'd assume again we're talking about a capsule the size of a basketball that either crashes back to Earth or gets caught in mid-air by a plane. That's how film was recovered from early spy satellites.

No, that's realtors.

"10 years ago we thought we were the only solar system with planets."

What?

Find me a university textbook that states that.

That's not what you said. You said "You switch them on and off by heating them up to change their conductivity. ", which is both utterly wrong and an amazing claim to make.
