Mary / Teresa he is not on oxygen as yet - he does still move around on his own - the getting off immunology was the Dr.s (Simon Cancer Center) choice he did suggest maybe Chicago and that they had newer clinical studies; I think his memory function has been affected as he does weird things - you have to keep repeating and getting were you have to spell everything out getting where i think i need a drawing pad and color pencils but i do not draw worth a _ ; he is much slower at riding his bike i notice down to the country store - but he won't admit to anything He mostly sits and watches TV - unless pushed - its as if he does not give a dam about anything - even keeping warm unless he can freely plug the kerosene salamander in and run it 24/7 thank goodness there is enough cracks in the place. He even leaves the top damper wide open as well as damper on the front electric blower and I have even caught him several times walking off leaving the furnace door wide open. The last month I have went to bed and said the hell with firing the furnance at 12-2-4-6 as he does not even attempt to help with that if he does fill it it he stuffs it so full ther is no air around the wood to burn - leaves both dampers open and by time I catch it it is totally burnt out of if not its smoldering and i have to fight to unpack it and through the wood out on to the floor to re-stiock it
