No Refills

A distraught senior citizen phoned her doctor’s office.

‘Is it true,’ she wanted to know, ‘that the medication you prescribed has to be taken for the rest of my life? ‘
‘Yes, I’m afraid so,’ the doctor told her.

There was a moment of silence before the senior lady replied, ‘I’m wondering, then, just how serious is my condition because this prescription is marked ‘NO REFILLS’.’
