I made sandwiches for awhile. I always put in extra meat. I had to quit though, I got a frozen shoulder from repetitive motion. It's a job for young people.
There are a lot of jobs like that. I’ve had physically demanding jobs most of my life, and have always cut, split and burnt wood. In between jobs I split wood for a friend who owns a tree service company. He had me splitting and throwing wood all day for 9 hours each day. I’ll tell you what, my wrist joints were literally creaking from the repetition of throwing the wood by the ends all day, several days in a row. I couldn’t fully straighten them for several days after I stopped. I’ve never bounced up so quick as I did when he said want to do some carpentry on my house instead? I can pay you more per hour!
