71, here, sonny.
See, @Alemart. We’ve gotcha surrounded.
I think maybe @mandog, my pseudo-mentor in Arch, is about 102. Then again, he was an Archlinux early-adopter (2007?). I have seen competent beginning-Archers as young as 9-10 post in the Arch Forums. And there are those way older than us old-fogies that run Garuda or Arch (lookin’ at you, @SGS). Personally, I like problem-solving things that keeps me feeling significantly more cognizant than those that don’t. Example: I always do simple math formulas in my head; do you?
The 1st reaction I normally have when I note a sub-teen or older than myself (line-drawing?), is oh shit, not again what a wonderful thing it is, that Linux & opensource (and closed) give those that wish it, an operating system of their own.
No reliance on anything other than the imagination. 
Other than my wife of 30 years, Linux is my longest lasting love-affair. And there are many others who feel the same. Many of them are here.
