13. I have some good news and some bad news. The bad news is: no member of you family has ever lived past age 60. The good news is: think of how much social security money you family has saved the rest of us! Anyway you just "celebrated" your 40th birthday (complete with all those lovely black balloons that read, "Over The Hill"). Since you are certian the grim reaper will visit you in 20 years, you decide to purchase an investment that will pay you $4,000 each year until you'reach room temperature" - that is - age 60. If this investment returns 6% to you, how much should you be willing to pay for it? ("pay for it", as in TODAY!)
