A middle aged woman has a heart attack and is taken to the hospital. While on the operating table she has a near-death experience. During that experience she sees God and asks if this is it. God says "No" and explains she has another 30-40 years to live.
Upon her recovery she decides to just stay in the hospital and have a facelift, liposuction, breast augmentation, and a tummy tuck. She even has someone come in and change her hair color. She figures she's got another 30-40 years, so she might as well make the most of it.
After recovery from her final operation she walks out of the hospital and is struck and killed by a speeding ambulance. She arrives in front of God again, and asks, "I thought you said I had another 30-40 years, what happened?"
God replies: "Sorry, I didn't recognize you."
