Should Humans Inhabit Mars?

Stephen Hawking warned that humans needed to colonize another planet within 1,000 years but quickly upgraded that figure by saying we have to do it within 100 years in order to avoid extinction.

There’s a problem with this plan: under almost no circumstance is colonizing another planet the best way to adapt to a problem on earth.

I guess many people are afraid of a doomsday scenario, where the Earth becomes weak and just cannot sustain life. Whether it’s because of nuclear war or massive global warming, a post-disaster Earth would be a lot more habitable than packing our suitcases, loading them into a spacecraft and zooming off to Mars.

Apart from the logistics of who gets to go on a 7 month space ride and what do we do when we get there, there are also ethical reasons behind even considering starting a colony on Mars or landing the first manned spacecraft on the planet.

Reading this article will give you reasons why we should travel to Mars.

Of course it goes without saying that there are risks involved; and you can read about them here.

There is a series entitled “Mars” which is a combination of a fact and fiction and I really enjoyed this show.

You can read a review here.

Whether you agree or not that we should sink billions of dollars into research to make it happen , it’s still an interesting discussion to have.

For example, “bastard” is frequently a term of endearment in Australia and isn’t really considered swearing. But saying this, gauge the room. You wouldn’t drop the f-bomb in front of gran, or a conservative executive.”

About a third of US adults don’t get enough sleep.

And sleep deprivation has serious consequences for your brain and body.

Many people think they can get by on less than seven to nine hours a night – the amount of sleep doctors recommend for most adults – or say they need to sleep less because of work or family obligations.

Most adults need seven to nine hours of sleep, and kids have to get even more, though needs do vary from person to person. Some incredibly rare people can actually get by on a few hours of sleep per night, while others on the opposite end of the spectrum are sometimes called “long sleepers” because they need 11 hours nightly.

But regardless of your body’s clock, a lack of sleep will cause your physical and mental health to suffer.

Here are 30 health consequences of sleep deprivation.
