As for preventative medical treatment: This one is a difficult topic. There’s a popular misconception that getting a lot of different blood tests and imaging scans is a good idea to identify conditions early, but most people don’t understand that these tests (including imagine) are prone to a lot of false positives. Excessive testing has been shown time and time again to lead to unnecessary interventions, leading to worse outcomes on average. A number of previously routine medical tests are now not recommended until later age or until other symptoms appear because routine testing was producing too many unnecessary interventions, producing a net negative benefit.
It’s a hard concept to wrap our heads around when we’re so attached to the idea that more testing means better information. It’s a huge problem in the alternative medicine community where podcast grifters will encourage people to get various tests like organic acid tests or various “levels” testing, then prescribe complex treatment programs with dozens of supplements. The people chasing these tests then throw themselves far out of balance with excess supplements while sinking thousands of dollars into repeat testing
