Investing in Life ins to use as senior settlement in retirement

Our financial planner is trying to talk us into buying our max life value in life insurance. In retirement we could use the life insurance as income for retirement by selling the policy and it is the only type of investment safe from creditors. I don’t know a whole lot about viaticals but have been searching the web. I was wondering if anyone out there has any personal experience, expertise or can point me to some helpful information.
