Under: Food & Lifestyle
History is filled with wondrous inventions that have changed our lives forever: the light bulb, the car, penicillin, the Internet. This has led to a belief in many that innovation can and will accomplish anything, and that it’s only a matter of time before all the fantastic technologies and ideas we dream of become a reality. While it is true that progress is an amazing thing, there are limits, and there are certain ideas that will simply never come to pass, no matter how cool they seem.
There are few among us who’ve never felt the slightest insecurity about our weight. Whether you feel you need to lose a few pounds or a few dozen, we’d all like an easy way to achieve our ideal weight. The “easy” part is what has given rise to the endless streams of fad diets promising us miraculous results.
It sounds good. Lose weight by just a few special tricks. Many even offer seductive claims like “eat as much as you like as often as you like” or “you can still eat cake.”
The trouble is that there’s just no easy way out. These diets never live up to their claims. They’re either based on bad science and can’t deliver on their promises, or they’re so restrictive that no sane being could stick to them, or perhaps both. In the end, the only solution to the weight problem is common sense. Cut down on junk food, exercise regularly, and don’t worry if you slip up now and then.
On paper, communism seems like the blueprint of an ideal society. Classes, borders, and all such artificial barriers between humanity are broken down. Everyone is equal, and no one wants for anything. In the communist ideal, the entire world would be one unified nation with everyone contributing to the greater good.
Sounds great, right?
Communism fails to take into account human failings, however. It makes little concession for things like greed or laziness. If every person on Earth was perfectly selfless and good-natured, communism would work, but that is not the case, and until it is, it’s unlikely communism will ever deliver on its grand promises.
Furthermore, the transition to communism is generally thought to require armed revolution against those currently in charge, and all that violence sort of runs counter to the “perfect world, love thy neighbor” philosophy communism espouses.
We all dreamed of jetpacks when we were kids. Strap a rocket engine to your back, press a button, and fly wherever you please — no one can deny the appeal of that. Aside from the obvious fun and cool factor, it’d be incredibly convenient. No traffic to worry about; it would just be you, the open sky, and the need for speed.
Jetpacks actually do exist, and they work, albeit in a very limited capacity. Daredevils use them for stunts, and a few very rare and very rich hobbyists use them just for fun.
Unfortunately, the dream of everyone using a jetpack to fly to work is unlikely to ever come to pass. The concept suffers from several fundamental flaws. The chief among these is the problem that the more fuel you carry, the harder it is to get off the ground. For this reason, jetpack flights can never last more than a few minutes — nowhere near long enough to use them for anything practical. They’re also extremely difficult to control and just downright dangerous.
