I have the utmost sympathy for you buddy. Two years ago I experienced a very similar situation. My Grandfather was my hero. A great man, a strong man, a hard man, but a very loving man. He was like a second father to me and until he was 97 years of age he was able to live on his own independantly doing his own shoping, cooking, cleaning, washing, ironing, etc until he finally became weak. He fought hard but finally withered away in hospital just before his 98th Birthday. He was so independant that he neglected a lot of the help from the nurses and doctors, which put more strain on him. He stopped eating, and then stopped drinking, in which time he was on the edge and finally lost the battle. I hope you're Grandfather will either make a full recovery if possible, or if not then pass away more peacefully than my Grandfather did. I know that I will not want to experience that again ever! My thoughts are with you Ryan.
