The old is coming back in NYC: architects and public health advocates are getting behind a new trend - stairs. Climbing stairs can burn more calories than jogging and the potential for stairs to transform spaces appeals to architects as well. Researchers report that if the average American spent 2 more minutes climbing stairs every day this calorie expenditure would offset the average annual weight gain.

Standard approaches to fighting obesity have not be hugely successful. Maybe there's hope for change if we can align public health goals with architectural or aesthetic ideals? I'll be on the lookout for attractive stairs now.
