Playing Your Age

A lady is having a bad day at the roulette tables in Vegas. She's down to her last $50. Exasperated, she exclaims to the whole table, 'What rotten luck I've had today! What in the world should I do now?'
A man standing next to her suggests, 'I don't know, why don't you play your age?'
He walks away, but moments later, his attention is grabbed by a great commotion at the roulette table. Maybe she won! He rushes back to the table and pushes his way through the crowd. The lady is lying limp on the floor, with the table operator kneeling over her. The man is stunned. He asks, 'What happened? Is she all right?'
The operator replies, 'I don't know. She put all her money on 36, and when 47 came up she just fainted!'
