Back from the orthopedist

After consulting with my orthopedist, I made a date for a total knee replacement on my left knee.  I've put this off for seven years, had a couple of temporary fixes, and gotten by.  But considering the fact that right now I have Cliff's insurance plus medicare, which means it will be almost totally paid for, I can't see putting it off any longer.  So in about a month, I'll be getting the deed done.  
The biggest concern I have is this:  I should forever stay off motorcycles once I've had this surgery.  We had a lot of plans for trips on the bike.  I wish we could find an affordable three-wheeled bike, or have a conversion done to our Gold Wing; because that would really cut the risks of injury to my knee.  I'm not promising I'll stay off motorcycles anyhow.  But I know I should.  
Other than that one concern, I'm ready, willing, and able.      
Between now and my surgery date I have to have some of my own blood collected so they can use it for me at the time of my surgery, and I have to get some pre-op tests done.  The time is going to fly by till the big day!
