I follow the health laws of the Bible; so I don't eat unclean foods, like pork, oysters, etc..
When my dad was working in Decator, Alabama, he was putting in a plant for 3M. One day, the engineers decided to goto a rib joint for supper. Along the way, one of the engineers, knowing that my dad did not eat pork, asked him what he would eat. My dad said that they'd probably have a salad or something to eat. The others wanted to know why he wouldn't be eating the ribs? He told that he followed God's food laws and didn't eat unclean meat. They poo-poo'ed him. Then my dad's boss who was a chemical engineer told them ab't a paper he had done on the internal workings of a pig (as a chemical factory). When he got done they decided to go eat somewhere else. [If you have a feed mill near you, or know someone who does, look up the cans of Drano, they are about the size of a half gallon of milk. I wondered why would anyone need that much? So, I took the can off the shelf and looked at the instructions on the back--for flushing put a pig!]
