I'm not sure where to post this so it landed here. I was watching a few youtube videos of queens guard and noticed that there is a substantial amount of postings about guards slipping and falling. Is there a reason for this? Several videos look like something that would happen walking on ice but it doesn't appear to be any. I figure someone here has had to have been posted and have an answer. I'm just curious. Also, how long are the shifts? I think the American old guard do 8 hour shifts, pretty much standard guard shifts, is it the same?
