I am a SWM, 63, and have never understood many older men.

95. It's odd. If your cousin is in good health and the two have similar interests,

It may be more of a companionship that she wants, and to her -and to him - the sex or "romance" is not a big deal. He gets an ego-boo and a good intellectual friendship, she gets a security and good intellectual friendship.
She might not want kids or what she sees as a younger man's aggressive activity.

Relationships are about many things, not just sexual attraction.

While squicky to those who think of marriage or living together as a partnership with benefits, some people and cultures don't see it that way.

For instance - my Father-in-law's last wife is only 5 years older than me, 20 years younger than her husband. However, they were both active in the same running and golf clubs, had similar hobbies and friends, and she was independently wealthy enough that it wouldn't seem she was being a gold-digger when they got together after his previous wife died. Laz, his sister, and she are actually still friends after FiL passed 8 years ago from a freak mosquito bite that gave him West Nile Virus.

All that being said, if there is a power imbalance involved, that is not a relationship, that's a attempt at a forced transaction, not a older person "being attracted to" a younger person.
