I know what you mean, Paul.. Doc retired me from work in June 2009, and booked me in at the hospital for right knee replacement, said that it would have to be done within 3 years.... I am still waiting... and the knee getting worse after 7 years on the waiting list.
Today is one of those bad days, where I am hobbling around with my walking stick, haven't been outside the door today.
Now, if I was a celebrity, or a football player, or such.... "Oh. Saturday afternoon ok?.. have you back on your feet by Monday..."
Yer, sure...
