All the luck.

Private health insurance is issued by a "for profit" insurance company
that is licensed by the state in which they sell policies. All private
health insurance is subject to a "medical Underwriting" process wher
the applicant's health history is used to determine if the person is
an acceptable risk to the company.

Public health insurance is by either a state or federal funded program
if the applicant meets certain qualifiers such as age (Medicare) or
income level (medicaid).
