I have come to the conclusion, if you are of menopause age, you are thrifty.  We are always thinking of ways to hang onto our money.   One idea came to mind the other day.  Someone told me this a very long time ago.  She said......  there are two sides of paper so be sure to use both sides.. 
Why do we write on one side, tear of the sheet and toss it away?  Now, that is recycled paper before it's recycled.  100% recycling.  Try it and save big.
