how been constipated?

I had this problem more as a child and young adult than I do in middle age, because I finally understood how important it is to get enough water -- three to four liters a day, even in the winter time -- so that your wastes don't get hard from your lower intestine drawing out too much moisture between bowel movements. In the summer we usually notice the need for liquid because it's hot and we're moving around more, but in winter we still need that water to keep our bodies running smoothly.
