Funny you should mention it... my wife has been on an “Outlander” kick of late so we were discussing what we’d do if we found ourselves stuck in 17th century. I reckon I remember enough from college and am handy enough with equipment to make myself useful as a blacksmith. However, her journalism degree wouldn’t help much back then so she figured she’d make soap, squat on some natural hot spring somewhere and pass herself off as a “healer” who, in reality just convinces people to pay her for a hot bath. Those kind of smarts are the reason I married her! I do wonder how many European wars could have been won with soap and decent shoes...
