Medication

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'.'
