You’d never know it just by looking, but my wife turned 40 this year. We don’t usually do big birthday celebrations, but 40 is a big one. Some people don’t handle getting older very well, but I think Kate is more OK with it than most. She is a special lady, so I wanted to do something special for her day. I didn’t think throwing her a huge party in the middle of a pandemic was the best idea. So, I bought her a sauna.

Your body is hard-wired to react to stress in ways meant to protect you against threats from predators and other aggressors. For example, think of a prehistoric caveman with a boar coming at him. These kinds of threats are rare today, but that doesn’t mean that life is free of stress.
