Old man was crying on a bench in the park. But the reason why is just insane

When I went to lunch today, I noticed old Bert sitting on a park bench sobbing his eyes out. I stopped and asked him what was wrong. 

He said, “I have a 25-year-old wife at home. She rubs my back every morning and then gets up and makes me pancakes, sausage, fresh fruit and freshly ground coffee.” 

I said, “Well, then why are you crying?” 

He continued, “She makes me homemade soup for lunch and my favorite brownies, cleans the house and then watches sports TV with me for the rest of the afternoon.” 

I said, “So, why are you crying?” 

He said, “For dinner she makes me a gourmet meal with wine and my favorite dessert and then makes love with me until the wee hours.” 

I said, “Well, why in the world would you be crying?” 

Bert said, “I can’t remember where I live!”
