Not really much else to add or say. Everyone is touched by this dreadful disease at one time or another. Best thing to do is what you already said, take it one day at a time. Spend time with the family especially them grandkids. If I'm not mistaken you have a granddaughter that likes riding in your sidecar, might want to try and take a ride with her (weather permitting). Hope you can enjoy everyday ahead and maybe prove the docs wrong, after all they only practice medicine.
Good luck Steve, it's a hard road you're on right now.
