Well, life insurance is a touchy topic because it outlines how your assets will be allocated after your death. So, you want to choose a plan that will best protect your assets and your loved-ones wellbeing after you pass away.
The difference between whole life and term life isurance is thus-
Whole Life carries a higher premium but it does not expire until. well, YOU expire. Term Life carries a lower premium, but it is only active for a fixed amount of time. However, you can withdraw the benefits at the end of the term. For example, many Term policies last for 30 years, and if you have, say a $250,000 policy, you can withdraw the earnings at the end of the term. If you don't mind me saying, you are at a tricky age. It may make sense for you to get term life, however, it is quite possible that you outlive your coverage, presumming that it is a 30 year plan. Then, you have the issue of what to do with your gains at that age. Do you want to be 85 and have to pay capital gains taxes if you should happen to withdraw? Also, who will benefit? Further, it would be virtually impossible to get a new policy at that age.
Whole Life will cost more, but the proceeds will accrue for as long as you live. Your basic dilemma, as morose as it may sound, is that you have to bet on whether you think you will outlive your coverage, should you choose Term coverage.
Life insurance is complex but that can be a good thing. For example, you can combine policies, and take out a less expensive Whole Life policy, with a cheaper premium, just to cover you for the remaining years should you outlive your term policy. Then, there are ways to structure how to allocate your gains an premium payments. For example, you can structure it so that your money goes into trust for your beneficiaries, or into IRA's for them, so that you die penniless, but your loved ones are already cared for. That is an attractive option for individuals who do not want their loved ones to incur high estate taxes when the proceeds get released unto them.
I would definitely see which plans AARP can offer you. They can set you up with something that is manageable for you and suits both your needs and those of your loved ones.
A big part of your decision will be based on whether or not you expect to outlive your coverage (and I hope you do!), should you decide on a 30-year Term policy. That said, the right advice from a qualified sales person will get you the info you need.
I know I said a lot here. But, there is a lot to say in order to understand your options. Hope that helps. Best of luck to you.
