Curate, connect, and discover
Pushing the button will cause you to almost always have perfect health.
Here's how it works: When you develop something that you consciously consider a health problem, the next time you sleep you will wake up next to your body. It is now dead. In a maximum of two hours a new body will form around you that is just how the previous one would have been without the problem. If you were sick, no longer sick. If you lost an arm, it's back. If you were born with one arm but want two, you have two now. If you decided that human bodies (or just yours) have a flawed design and have ideas for how it could be improved, you have the improvements. Yes, this can be things about your mind that you want to change. Etc. You can figure this out I think. Of course, you will need to do something about the corpses. And each time this happens, you look just slightly more uncanny.
