Some discussion about Amish living here in other threads. Trust me, no fun if you ask me. Yes, nostalgia is great but the real thing is different. We lived off-grid for 12+ years and truth is, it sucked! Compost toilets are the pits.
I respect them totally but no way I'd want to live my entire life that way. There is a reason we went to electricity and indoor plumbing. Nice to have 21st century things like a toilet that flushes, running water and electricity.
