An old man is sitting on a park bench crying

An old man is sitting on a park bench crying. A young
man is walking by and asks him why he`s crying. The old man says, "I`m
retired and I have lots of money, a huge luxury apartment, a beautiful
25 year old wife who loves me and has sex with me twice a day."

The young man says, "Well then why the hell are you crying!?"

The old man replies, "I can`t remember where I live!"
