LOl your funny and in denial , I am older and I have seen a lot of people with old age issue which you just admitted Joe has
If you think freezing up like joe has done several time in public and mumbling and rambling on telling unbelievable stories about himself and his family asking where dead people are is normal for a 80 year old then I have a bridge in NYC I want to sell you.
My mother is 85 years old and forgets things from time to time but shes hasn't got the issues Joe has,
Seriously you cannot see a issue here ?
