I live on the ground floor of a condo building, and it somehow seems to take 3 - 4 minutes just to walk down one flight of stairs and get to my bike or get in my car. It's like I'm gong through a time warp, and people keep telling me to slow down when I walk because I walk so fast. You could be most of the way to work in the amount of time it takes me to go back upstairs and get whatever I left behind and get back downstairs again.
