Do you exercise daily?

I have ben an avid walker for about 11 years...I walked up to 7 miles a day every day...lately I have been having trouble working it into my schedule which is so unlike me...but I am back to the past 6 days doing at least 4.5 miles...I love it...and feel really bad when I don't do it..but somehow I have slipped from my 11 year habit...and now I just want to get back to it!!!
