My widowed FIL (age 75) married a sister in his hall that was 42. We were all totally against the marriage. He was well to do and newly baptized. Within 3 years (of living on McDonalds, Wendys and Burger King) he was diagnosed with advanced prostate cancer. He died shortly after the diagnosis. He had a will that gave everything to his two children (my husband at the time). However, since the will was drawn up a year before his new marriage it was worthless. She got EVERYTHING (including the salt and pepper shakers and family pictures). He had a large life insurance policy made out to his daughter, but somehow the new wife ended up with that too (long story, but true). The family took her to the elders and then took her to court, however in CO law the wife gets everything if there is not a will (and his will was not valid).
There is no fool like an old fool
I am totally for marrying at any age, but only for Love. No other reasons are good enough in my book.
