Unfortunately, no, you cannot. Additionally, I would ask why would you want specifically term insurance? Here's why. At 85, with life expectancy what it is, if you could buy term coverage, what would the term be? The shortest term plan is 10 years (yes, there are a couple of 5 year plans but they are priced like 10 year plans). So, with 10 year term, you are guessing that you will pass away while the plan is still in force. First, it will cost a zillion dollars and, second, you might outlive it. Ouch! If you could purchase a longer term plan you would spend a zillion+ dollars and who knows if you would outlive it. Guessing is not good where this is concerned. What I am getting at is that you could do better than to aim for term insurance.
Were you to look at Universal Life insurance or Whole Life insurance, there would at least be the guarantee of a death benefit since you cannot outlive a policy with an end date of age 121. UL and WL take your question to the place of practicality. Term does not.
