I think the danger comes in the fact that your body has no time to recover. Its OK to work 6 days a week for a short time or even every once in awhile. However when it becomes a forced reality that you HAVE TO work 6 days a week is when it becomes an issue. Our bodies need time to rest and recover you can't do that with only one day off a week.
