I last shared this on Google+ two years ago. It was time to
   share it again How long is a billionth of a second? 11.8 inches
   long.

   (that's a nanosecond)

   How long is a microsecond?

   984 feet long.

   So if you are ever doing programming and you are wasting
   microseconds (ms) - you'll know just how much you're wasting.

   These aren't theoretical - this is reality. And it's pretty
   cool.
