occasionally i'll walk outside for like 5 minutes to get some fresh air, but i go with some other people from the team so i don't feel like the only slacker. otherwise i only really get up to go to the bathroom or when we go down for the gym
when i was in retail eons ago, i used to go some workdays working 13/14 hour shifts with no break. now all i do all day is sit and standing time is a premium lol
