That women should marry a guy five years younger to her so that they can die more or less the same time instead of getting married to a man 10 years older than you so that you don't end up being a widow for a lage part of your old age... Actually it is true.. My both grandfathers died ages ago and now my both grandmothers have been widows for nearly twenty years.. They were around 5 years younger than their husbands.. They are now in their late eighties.
