For those kvelling over the prospect of octogenarians marrying 20 somethings. Check out the details. You will find that in many cases the kallah was a widow with children to bring up and married an older man rather than have no chance of remarrying.
A story I heard – it may or may not be true, so I will not give the name that was mentioned to me. A European Gadol a hundred plus years ago approached a young woman as a shidduch for his son, citing the boy’s yichus as the Gadol’s son. The young woman reasoned, why should I settle for the son? Why not the father? So they married and had children, but the Gadol was so much older that he could scarcely be a father to them. As a result, one of the sons went off the derech and became a fervent Maskil, doing untold damage precisely because the maskilim could say, “Look at his father, and now he’s seen the light and joined the Haskalah.”
So – consider all the angles before you jump to judgement.
