The old man

a man is walking through the park one day when he sees an old man sitting on a park bench crying. He approaches him and says
"you alright mate wats wrong?"
"is your pension not through yet?"
the old man sobbing replies
"no im a millionaire money is no object to me"
the man then asks him,
"is it your health thats making you sad?"
the old man replies
"no im fit as a flea, i run ten miles every day"
The man nods knowingly and says
"aagh i know whats wrong with you.. its women trouble?"
the old man mystifies him by replying
"no i have a gorgeous 21 year old wife waiting on me at home!"
the man then stops, "wait a minute" he says "your totally minted, you have a stunning wife and are in peak physical condition! what the hell are you crying about?"
the old man bursts into tears again and says
"i cant remember where i live!!!"
