Welcome CarolJose1. Lots of us here have had hip replacements. Mine is now ten years old and going strong. My only gripe is that it sets off the alarms at airport security and they insist on patting me down! But it's a small price to pay for absence of pain.
I hope you find a weight-loss programe that suits you - just don't be tempted by faddy crash diets! I have been losing weight recently with Weightwatchers On-line. I also found the 5:2 diet very effective a few years ago. I am a serial dieter and would like to get down to a sensible weight and stay there! Good luck to you. 
Does anyone use the Eco wash function on their dishwasher?
World Class Museums - why are they free to everyone?

Actually, I am not planning on doing it just yet.
