This week Jeff's mom, Barb, and Jack's mom, Toots, are on the podcast to discuss knees.  Barb had a total knee replacement 2 months ago and Jack has had 4 surgeries on his knees.  We go over their various surgeries, the causes, and the difficulties.  If anyone has any questions about knee surgeries, ask us on Twitter or Facebook and we'll get our team of knee veterans to answer it!
