thank you for sharing--I definitely could use some of those ideas with 2 replacement knees. And I'm going to share this with my water wellness folks--several fall frequently and it's so darn dangerous. BTW, I highly recommend checking around for a water wellness class--I work at the local little hospital in the therapy pool--it makes such a big difference for all of us. And don't think that is your local medical center has a PT pool you have to have doctors orders--call and check--my classes do not require a doctors orders--just your choice.
