I asked my grandmother when she was about 90 years old (2006-ish) what she thought was the most amazing invention during her lifetime. Answer: indoor toilet.

I was telling this story to another friend of mine 5 or 6 years later. She was about 92 At the time and blurted out, “indoor toilet!” So, I apologized—thinking I’d already shared time story with her. But she quickly told me that was *her* answer.

So: important stuff!
