I'm likely the oldest person in this thread, as I started this journey in 1977. I went through Military service, then Academics (physics/mathematics), then bailed to work in the tech industry in the mid 90s and haven't looked back.

And I still do.

OG Internet guys like me (and presumably you) have nothing to fear, as long as we keep our bits flowing. Trust me. If you keep active, the mind stays sharp. I've been everything from Chief SysAdmin to Principle Engineer. It's yours to take it, keep it, and stay in it.

Youth is great, except they ALWAYS FORGET GODEL AND TURING. Damn. I have had to have the same conversation a bajillion times....
