It turns out that human bodies must be properly reintroduced to earth's magnetic field. In recent years, scientists at NASA have learned how to facilitate this physical readjustment. They now have astronauts change into special suits embedded with magnets as soon as they land. They slip into their orange suits and voila--they're ready for cameras!

There is a great deal we are learning about magnets, and it's not just to help those who've blasted off into space for a while. Magnetic wraps have been used for decades to help racehorses heal after injuries. There is plenty of anecdotal evidence from trainers to support continued use of magnetic therapy for horses. Horses don't tend to say much about their beliefs, so it's hard to point to placebo effect as a possible explanation.

The most compelling idea about magnetic therapy is that we may need it now more than ever. We used to walk barefoot in forests and plains. We had direct contact with earth as we slept, hunted, and harvested. We were surrounded by vegetation and natural rock formations.

Not anymore. We've built concrete sidewalks, roadways, foundations, and buildings. We travel in cars and trains, essentially encapsulating ourselves. We've created a world of barriers between earth's natural forces and our bodies. It's reasonable to consider that this may be affecting us physically in ways that are difficult to diagnose.

The earth has so much to teach us. Sometimes we know what works long before we understand why it does so.

We've never questioned fact that being surrounded by nature helps us feel soothed, refreshed, and invigorated. Scientific research now shows us more specifically how earth helps us feel better. We benefit from negative ions near ocean, our brains respond to binaural beats present near waterfalls or during rainstorms, and our bodies react positively to a restored connection to magnetic forces.

I'm not likely to latch onto latest pharmaceuticals or tout benefits of new-fangled remedies. But old ones? There's no big company poised to reap huge rewards by promoting them, and consequently, we're not likely to hear about them on evening news or be bombarded with television commercials praising their potent power. I always like supporting underdog, and in this case, that underdog is backed up by plenty of science of unprofitable kind.

We would do well to restore our connection to earth and powerful forces that help us maintain our health naturally. How wonderful that we can benefit from negative ions, binaural beats and magnetism without dealing with health insurance or spending a lot of money at drugstore.

The next time you take a walk in woods, stroll along beach, or stretch out in a meadow, remember magic of magnetism. Recapture wonder you had as a child, and celebrate fact that sometimes simplest solutions are still ones that fill us with awe.

Apart from asteroids, there are also other menacing-to-hit-Earth objects including comets. Remember comet Shoemaker-Levy9? It wanted to obtain a better view of Jupiter. The result: engulfed by planet that is, comet simply crashed into Jupiter. This may happen to Earth too. If a comet were to hit Earth, it would be a real disaster. Extinction of life quasi-instantly! And humans for sure do not have technology to avoid a comet impact.

If we do not want to be extinct, we will have to flee. We have to go elsewhere. But where? Where next?
