My dad is 70 this year and has around $40k of savings for retirement. He does not have a hospital plan and getting it now will be too expensive. What are some ways to grow his money?

Wealth protection is more important for your father at this point in his life than wealth accumulation. Would you want his funds from investment/retirement savings to be wiped out because of ONE medical bill?

It is best you assist him to upgrade his Medishield plan with an integrated shield plan ASAP. Your concern should be more on his insurability rather than the cost of the of the hospital plan.

At least get the plan that covered the public hospitals. At the age of 70, touch wood if something happens and no Medishield plan, the hospital bill can wipe out that 40k easily.
