The Bathtub Test

During a visit to my doctor, I asked him, "How do you determine whether
or not an older person should be put in an old age home?"
"Well," he said, "we fill up a bathtub, then we offer a teaspoon, a
teacup and a bucket to the person to empty the bathtub."
"Oh, I understand," I said. "A normal person would use the bucket
because it is bigger than the spoon or the teacup."
"No" he said. "A normal person would pull the plug. Do you want a bed
near the window?"
