Hmm, y'all sound healthy!
I do have to walk about 15 minutes to and from the station to go to work, but I don't think it is very healthy, because the train is like a can of sardines, with all the people stuffed into it... (Plus, in Japan, for some reason it seems that people do not cover their mouths when they cough...)
Mnnesota sounds like it has real winters! No snow here, and not that cold - I want some snow...
