My dad is in his mid 60's, and I'm pretty convinced he's going to be like that. He's not a software engineer, mostly a mechanical engineer, but it's pretty rare that I talk to him and he's not hacking on something mechanical. I'm not talking just woodshop stuff; he is actually doing math and calculations for little things that he's building. He is an engineer by blood that happened to make a career out of it.
