Our hambeast housemate is always super out of breath the minute he gets in the door. From the bus stop to our place is 5 minutes for me walking with a baby on my back and kid holding my hand.....10mins waddling for it I guess. A few times we made a point of going "ummm are you OK?" And it would just sputter muh excuses and we would just shake our head because we know gasping for air after walking a few minutes isn't normal.
