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.

But I could have been anything even though at that time it may have been a little bit harder to convince employers of that.
Of course though, women have been working for centuries outside of the home assisting on farms, working in the fields and other hard labour tasks.
This article fills you in on the lives of women working as truckers, a lobster fisherman, firefighters, butchers, mine operators and other areas of work usually considered to be “manly”.
If you had a choice to reboot your career, what would you choose? I like to think that being a mechanic would be an interesting alternative to fetching my boss’s coffee. Which of course now, I fetch my own.
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.
