Honestly it kind of sucks.
I always wanted a kid but it requires a partner who is able to be a parent and I have never had such a partner.
I had a pretty fucked up childhood and I wanted someone who could be a good mother to a child and everyone I've dated who had the ability to be a good mother was not capable of giving birth for one reason or another and everyone I've dated who's capable of giving birth was not capable of being a good mother for one reason or another.
I know it's not too late for me but it's getting pretty damn close.
Also, if you have a cast iron pan that is extremely rusted, get a brass bristle drill attachment and blast all the rust off with it.
After you have finished that and cleaned it, season it like the other poster mentioned and it will be as smooth as almost any Teflon you've ever used.
