Elevation

I know that I am out of shape. I know that I should exercise and I don't. But when we were in TX, I never gasped for air like I do here. It is embarassing. So, I looked up the elevation of Calgary and compared it to Houston. Calgary's elevation is 3438.3 ft while Houston's is 43 ft!! So, while I will continue to promise myself to start working out (like I have been for years), at least I know the elevation can be blamed as much or more than my fitness level. :)
