Hi Grreat Teacher...just imagine where you'd be if the individuals caring for you hadn't gone on to higher education. Isn't modern medicine & technology awesome?
Your having a total hip replacement is like replacing a transmission & differential in a vehicle...the difference is the former is soo much more complex & requires more skill, intelligence & TLC...it sounds like you're in the best of hands!
Wishing you a speedy recovery & smoother movement!
