One day I was on the beach when I saw two of my students. After their swim they collected a huge bucket of water and began to bring it home. These students that I saw were about 8 years old and tiny; it looks like they have no muscles at all.
I caught up with them and offered to help carry the big bucket of saltwater, and they refused to give it to me. I felt really bad for them since it was a huge walk uphill, and then quite a big distance further to their houses, overall, about a mile away.
I finally asked why they were carrying the buckets, and I learned my new fact about pigs. Pigs are bathed in saltwater. (Horses are too. People ride their horses into the ocean to bathe them.)
The other fun fact I learned about pigs is, you can trade someone a very large male pig for a cow.
The more you know.
