Unfortunately, I am not on Medicare as I always worked for the State of Illinois and didn't accumulate enough credits in Social Security to qualify. Instead, I have the same health insurance I had when I was working, which is actually better than Medicare, because it's free (no insurance premiums) -- a perk that Illinois offers or used to offer to retirees with more than 20 years of service. I don't know if there are other programs that are similar to Silver Sneakers for seniors, but I can do an Internet search. I thought maybe I could get in under my wife's eligibility, but they won't let me.
