I just turned 65 and I'm trying to decide whether or not to start Social Security or not. If I wait until I'm 67 I will gain $300 per month which is definitely be better. My problem is having to sign up for Medicare and having to pay out of pocket until I start SS. I was married for 34 years before getting a divorce. Can I draw on my ex-husband's benefits to cover the cost of my Medicare so that I can wait until I'm 67 to start to draw my SS?
