"It is physically impossible for pigs to look up to the sky. "

Spring Valley, Liddle Facts, Fact #79

This is a fact I discovered today. It's a fact that I find quite upsetting.

This means that unless a pig is trotting up a hill at just the right incline, or happens to catch a glimpse as s/he is rolling in the mud, or sees a reflection as s/he is drinking from his/her trough, or a kind person holds a mirror up to a pig at such an angle that the sky was reflected in it, a pig will hardly ever see the sky.

It is so sad. Imagine not being able to see the sky.
