in reply to Perl is my cast iron pan
I particularly like this analogy cause in the 60's and 70's people were getting rid of cast-iron frying pans, or leaving them in the bottom drawer for years at a time, because they were heavy, unlike the nice new aluminum or teflon pans.
Now those same pans are getting regular use, or pans 50 years older. Hard for anything to go wrong with a cast-iron frying pan.
