As people get older, age difference means less and less. Obviously, a 40-year-old marrying a 20-year-old will be questioned, while no one will think twice about an 80-year-old marrying a 60-year-old.
Habang tumatanda ang tao, hindi na masyadong isinasaalang-alang ang agwat ng edad. Maaaring may magtaka kung ang ang isang 40 taon ay magasawa ng 20 taon, pero walang magtataka kung ang isang 80 taong gulang ay magasawa ng 60 taong gulang.
