Without the giant letters I'd be lost.

It's easy to feel incredibly insignificant watching this video of astronauts sightseeing from the International Space Station. Especially after it dawns on you that you're in one of the shots, taken as you sat in front of a computer, passing the time by clicking on links to viral cat videos and feeling insignificant. Other than that, though, pretty cool!

The two American astronauts are so casual it makes it seem like their jobs aren't all that difficult.  I guess even flying through space at 60,000 mph gets to be like any other job. It's possible these guys have one eye on the clock, waiting for their Russian replacements to punch in, so they can open their laptops and watch viral cat videos.
