I listened to a radio 4 programme about this the other day, where some office manager was extolling the virtues of walking meetings with colleagues. So, if I was discussing a complex issue with, say, 4 colleagues, we'd chunder around the workplace, car park, park or street maybe while we talked and listened. We'd probably need umbrellas, or, if we were inside, we'd need to consider the quality of the flooring after multiple meetings. Also, we'd get good at typing or dictating as we walked because we'd presumably arrive at some conclusions/decisions during our walking meeting that would need recording or acting upon - or not. We'd get ever so fit and healthy, and less sedentary, and with our new found energy we could move some real mountains that need shifting.
