First, I'll limit my discussion on this topic. This thread nor this website are not the best forums for involved discussions of insurance topics.

I'm not a fan of people using term insurance, a product with a limited life by design to solve a permanent problem. It would be like taking a trip from New York to Los Angeles in a car that would take one only to Kansas City.
The real question is what life insurance needs ... what would happen - financially - to a family if one member dies at each stage of life? IMHO it is rare for a person's needs to completely disappear at any point in his/her life. Many things can happen after the kids are grown and the house is paid off. Often these days, the kids return to the nest, the parents decide on a different home or -- a biggie -- medical expenses during the senior years especially nonmedical care at home or in a nursing home (@ $5,000 to $10,000 per month).
Even without the above expenses, what about pension plans or social security? Most pension plans offer the pensioner one amount per month for the rest of his/her life but a lesser amount per month if the pensioner chooses the joint lives of himself/herself and spouse. SS survivor benefits are also lower.
My "understood or not" comment refers to the many people who refuse to realize the risks later in life with a "that is not going to happen to me" attitude.
Talk to the spouse or other close family member of someone who has spent a year in a nursing home.

Historically the return inside a Whole Life policy is extremely poor. These days with near zero interest rate on bank savings, some of the older policies (Whole life or universal life) offered guaranteed minimums of 2% or 3%.
But you are very correct that taking a long-term view of one's financial life with due consideration to the risks - even risks we cannot foresee is the best way to plan ahead. Talking to a qualified, unbiased third party is a good step and worth the money.
