I visited Vietnam this December with family. The first thing I noticed when we arrived in Hanoi (and then across the country) are the tiny plastic stools found in public spaces. They come in all colours of molded plastic, and adorably miniscule sizes. The stools seem to be central to most daily activities, barring no age. I saw shopkeepers run their businesses, old women stare at everyone with a mixture of silent wisdom and boredom, teenagers drinking iced coffee or having a smoke, and street food customers being served on these stools.
The objectnerd in me cant help telling you that what's great about this cultural phenomenon is that it maintains good posture and digestion, and helps keep joints in use (much like squatting toilets!!). However, they aren't very great for someone who may be physically disabled in any way (such as my grandmother).
