There is evidence that standing is better for the human body than sitting. For work we have standing desks for computer work and such. Some aim to stand 8+ hours a day.
What about for other activities? How do the unemployed, retired, and homemarkers get in enough standing? Are there good ways to stand while reading a book, or sipping a coffee and enjoying the dawn?
Probably the best way would be eliminating reliance on cars and creating walkable neighborhoods with stores, restaurants, and services within walking distance, in the US anyway. Did people ever, throughout human history, just stand around the house?
