An experiment: buy two pressure cookers. See what happens.
If I bought 2 more pressure cookers, I'd have to get a wife to help operate them and plumb in the gas for another stove, since the ones I have already take up 4 hobs.
Nope. Safer to starve than buy 2 more pressure cookers.
You have to think through the implications and after effects.
I ain't getting married again. I wouldn't mind having another stove though...
