I have many pieces of well-used nonstick cookware well over a decade old, which are in pretty much the same condition as when I bought them. This includes cheap IKEA pans that my kids used. Some of them get used literally every day. We don't overheat them, and don't use metal utensils in them, and there's no reason they can't last forever.

Regardless, you can eat the entire coating off of your pan, and there will be no detectable fluorinated compounds in your blood. PTFE is completely inert and indigestible. It is widely used in medical implants inside people's bodies, with no detectable leaching of any chemicals.

Hmm, sounds like you've got lucky with your pans - everyone I've ever mentioned this too has had the same problem with non-stick pans! Lifetime of 6-12 months tops :/

I never did use metal utensils with them; it might be I overheated some, but certainly not all, and a pan isn't much use if you can't get it hot!

I don't think I'm lucky, but there is definitely a cost. The cost is that I'm a fucking asshole about my nonstick pots and pans. I keep my stash separate from the rest of the family, I get grumpy if I catch anyone using it, and god forbid anyone scratches my shit.

I buy separate stuff for my kids, and my wife has her own favorite pan.

Of course there's no need to be an asshole like me. But I think it's eminently doable for everyone. I do believe keeping the temperature down is key to longevity, especially for cheaper cookware with simpler two-layer nonstick coating systems. I have a lot of these too, and I just avoid going over 300 deg F or so. No problems so far.
