Weirdly, the mortality rates from surgeries can go up with much older doctors, for a variety of reasons, but mostly because they have lower volume of work so aren't as in practice and may not be current on latest techniques that may be less invasive or higher success rate. It could also be older people like having older doctors and the mortality rate is higher with older people getting surgery. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1856535/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1856535/ There is probably a statistical sweet spot, where someone has years of experience, is active enough to be up on the latest techniques, or at least learns the new techniques and adopts them. Parallels can be drawn between this and tech workers I'm sure.
