Oops I'm officially old

Holy sheeit, I'm old. My medicare card arrived in the mail today, welcoming me to old age, feebleness and government red tape.. Not sure how I feel about it. Old age doesn't bother me but the fear of having something wrong and having to depend on medicare for my medical and prescriptions just scares the bejesus out of me. My wife has been on medicare for a year and between my work related insurance and medicare they have still not decided who is our primary coverage. Interesting but frustrating too. Typical over kill. Each of the companies has millions of workers, none of which give a good frig what goes on and who is what. They have so many employees that no one knows what's going on anymore.
