Ever heard of this before?

I know its been forever since my last post, but here goes.

I drove up to the ol' Advance Auto Parts the other day to pick up some Lucas Fuel Injector cleaner. Usually drop it in every 5,000 or so, seems to keep things running smoothly. But while I was there a thought occured to me.
"I've never changed my brakes on this truck, NEVER!"
Now what makes this thought so deserving of that exclamation point you might ask?
My truck has 103,152 miles on it...that's why.
On top of never changing them, I've never even had them looked at. soooo I asked one of the guys in advance to check em out for me. Cuz honestly, I just didn't know what to look for other than a squealing sound.
So he proceeds to round my truck, checking all the rotors and inspecting the pads as best he can with the wheels in the way. He looks at me and says..."How old did you say this truck was?" I said its a 2000.
He replies: "Hmm. And how many miles on it?" Again I tell him 103 xxx. After looking at me somewhat puzzled he tells me "I've never seen brake pads last this long before."

So here's my question. Has anyone ever gotten this kind of brake life out of their trucks before, besides me?

I've never heard a single squeal, never had trouble stopping, and the rotors don't have a single groove on them. They feel brand new. As for the brake pads, they still got quite a bit of life left in them.
They are the original brakes that came on my truck when I bought in the summer of 2000 with 41 miles on the truck.
