I think there's a time when the human mind begins to well... you know what I mean.
Yeah, I know what you mean (I turn 40 this month), but I hope that there's no major limit on that sort of learning this side of 70 or so. If I ever find myself in a nursing home, unable stop my HD2 tri-vid display (or whatever) from blinking 12:00, that'll be my cue to "End Function" <g>. Until then, I intend to keep on learning...
I was just told by a professional coder that I'm too old to learn to take on programming seriously.
