Actually many women prefer older men, it gives them the sense of maturity and security. This is extremely important for women. A girl might date a young fashionable handsome gym trainer but she is more likely to marry an older sedate nerdy looking doctor. Don't take my word for it you can try polling in a female forum and verify this.
As for the guy being 60, chronological age and biological age can have marked differences. A guy who eats well, exercises regularly and have young looking parents can look much younger than his actual age. Look at Xie Xian or Fei Yu Ching. They can certainly romance women barely old enough to be their grand daughters.
Also we can't neglect that some people have Oedipus/Electra like complexes which compels them to fall for older women/men resembling their parent. Research has also shown that women with close ties to their Dads tend to pick men who resemble their fathers. Which is why based on the above points we can't rule out the possibility of younger women being attracted to older men.
However the take away lesson in this case is that this man went to look for love in the wrong place with the wrong type of girl. And in cases like this, the woman will most likely come back to contest for his estate after the guy kicks the bucket, meanwhile she'll likely be off romancing other potential chai taos and/or bf. That's how things work with many of these girls.
If this woman is really devious she might have fed this guy lots of high cholesterol, high salt & high carbo foods over the years they have been together. At such an age putting on lots of weight causes much stress to the heart and if he already has some pre existing conditions like obesity it will be terrible. Further aggravation through emotional distress will probably trigger a seizure effectively. Think this is far fetched and out of a novel?Read these and see how people murder by inducing heart failure and how even air pollution can cause it. Ask the lawyers here how difficult would it be to indict such an offender in absence of a witness.
