I see what you mean but it's more nuanced than that in my case. It's not like he turned 50 and suddenly stopped coding. I'm talking about a real nerd, a person who codes even on their free time. And he still writes code in other projects, he's a consultant, but in our project he's not touching any code, only advising. And he's 50+ now so he has 15 more years until retirement. Of course I've seen people here work beyond retirement because our field is so easy on the body.
