Once I get into work I almost never get out again until after 7 pm so I know what you mean. My office building is on a hill and we are surrounded by several medical faclities. They must pay their employees to go take a walk because all day long I see groups of them walking walking walking up and down the hill. I curse them as I drive by in my car wink.
I rarely walk outside but I am pretty good with the treadmill at home. And I have been going to the gym with a personal trainer 2x a week for 3 years. Not much noticeable weight loss (actually not any, truth be told) from that but I at least can carry my own luggage! And isn't that what its all about for the folks on this board? Being able to travel and maintain our physical ability to do it for as long as possible? Carpe Diem!
