I am 58yrs old and pay $250 monthly for $690 000 cover. Originally the policy was around $50 for $340 000 over 20 yrs ago.
I took it out to cover my mortgage when I had a young family. Since then I been diagnosed with a Leukemia. The insurance has been a great support and one less thing to worry about. The only thing now is my wife still looks great and will be totally cashed up when I kick it . lol.
