HAVE AN INSURANCE AGENT YOU TRUST AND LET THEM HANDLE YOUR MEDICARE, HUMANA Rx PLAN or whatever, AND YOUR  basic insurance (mine is AETNA).  I talk to my insurance guy at least once a month and he keeps telling me whenever I get phone calls about medicare applications, just start telling them all your life history, etc., and they will hang up - - - and they DO !!!  They want your personal information, they're not even WITH actual medicare most of the time, and I (regardless of this article) would NEVER depend on the information from the FEDERAL gubmint either.  After all, they're the ones scamming everyone !!!!!!!!!!

Be smart, use your head, and NEVER buy insurance over the phone.
