Insuring the Elderly

An officemate is trying to buy insurance for her 65-year old father and it seems insuring the elderly require more expensive premiums, since basically, you are looking at a short payment range and short shelf life. So we are trying to look for cheap life insurance for senior citizens, even health insurance plans are so expensive and so strict. I know it's practical for business but a bit unfair since the elderly, like babies, need them the most.
