Felicia Ackerman, PhD, Professor of Philosophy at Brown University, wrote in her chapter "Assisted Suicide, Terminal Illness, Severe Disability, and the Double Standard," that appeared in the 1998 book Physician Assisted Suicide: Expanding the Debate:

“Appeals to privacy and autonomy are characteristic of assisted-suicide advocates… But why not apply them to all competent adults? If the issues are really autonomy and privacy, then why legalize suicide assistance only for the terminally ill? Why not grant this right of privacy equally to the young and healthy–the very people our society values most–if they come to decide, for whatever reason, that they do not want to go on living? Such people could doubtless use suicide assistance in the form of prescriptions for lethal drugs, advice about administration, etc. What factors could justify granting this right of privacy only to the terminally ill?”
