I have a good friend who has stg 4 lung cancer and is on chemo at this time.  I usually try to see him every week or so.  When talking with him you would never know there is anything wrong with him.  He always was a cut up and still has that attitude.  Last week he purchased a 1955 Ford car to fix up.  He says he feels good and isn't going to give up.  He is an inspiration to me.       

He and his wife did go to the funeral home a few weeks ago and make arrangements.  Of course it would probably be good for most of us older folks to do that.    

Far as selling your trucks, etc  if you feel like it it would probably be good for you to help get this done.  Might even take your mind off of things.  I am sure it would help your loved ones as it might be hard for them to do this down the road.  

Our prayers are with you.
