Knee surgery

My husband is getting his knee surgery end of this month at the latest.  He is fine with the thought of surgery but was told he may need a cadaver part to repair and he is totally creeped out about it!  Nothing I can say is helping much, but he is trying to get over it.  He can opt for a part from his own body and that is still not helping him cope because he needs to call and let the Dr. know his decision. I think he doesn't want to sound like a baby about it or something and is putting it off till monday to decide wether to call Dr. or not.  He even admited to me that if I had to have a cadaver part put in me , where ever it was he wouldn't touch that area! LOL! Oh well, I still would rather have it than have another spot cut into! If I can't see it, smell it or taste it , why care where it came from? But I have to feel for my husband because he really is CREEPED OUT about it!  Hope all of my friends here are having a good day! Keep safe and enjoy the little things when ever you can!  :  )
