On average, how long can a 81 y/o male live whos been recently diagosed with parkinsons. He also has COPD and had many skin cancers removed.
Was very active untill he was diagnosed a few months ago. Main reason I ask is b/c he often seems out of touch with his surroundings, i.e. he'll stare straight ahead and you have to say something to him several times to get him to notice. He's been acting "silly" or...kind of goofy I guess you could say at time. he's always been a joker, but lately he just doesn't seem to make much sense
