Dangerous in a sense: costs money right now, we would have to deal with it. My friend once said: “no one is healthy, your doctor just does not have the testing resolution to find the issues” and in 3 years you get parkinsons…

That's too cynical. In reality, you're going to die with a number of completely benign issues. The more issues you find and try to interfere, the more likely you are to have a negative impact.

We not only can't find all issues, we can find more other issues than are ever going to be an actual problem.

But it's not really a money issue (not in a lot of cases anyway) - where it leads to better outcomes, doctors do aim for overdiagnosing to a certain % to cover cases which would be otherwise missed.
