Should there be an age related standard regarding the seriousness of sexual harassment allegations?

John Conyers has been accused of sexual harassment. The linked article makes references to incidences that occurred two or three years ago.
That would have made Connors about 85 years old.
I could be wrong, but I bet there is probably not enough Viagra on Earth to make an 85 year old guy a true threat, if not a joke, to any female.
It is sort of like being named in a paternity suit.
If I was 30, I would be sweating bullets.
If I was 85, I might be saying, “Well, it seemed like a good idea at the time”
Isn’t there an age where you have to figure it’s sort of pathetic?
