you can if you have an insurable intrseet , talk to your local agent they’ll be able to tell you how to go about getting it. have you ever seen or listened to dave ramsey? i listen to his show and he is adamant that anyone over the age of 60 have long-term care ins even if they are millionaires because it is so expensive. in the past year both of my grandparents have passed away and we were lucky enough to be able to keep them at home but it still cost approx. $7500 per month. luckily for us, our grandparents had planned well for that part of their lives and it wasn’t an issue. maybe if you can spell it out to your parents about how it would affect your families (yours and your brothers) to have to cover those extra costs along with regular living expenses, kids in college, etc? are you guys church members? maybe they could try talking to your parents.
