Another growing concern is the amount of brothers marrying very young sisters, some widowed no longer than six months taking up with sisters half their age. |
WHY is this a 'concern'? First there is absolutely nothing wrong with an age gap - either way? Secondly the woman (or man) always has the option of saying 'get lost' or whatever.
Most people who believe that age difference is a problem have a problem with jealously. Either they are jealous that their mate is getting (or seeking) the attention of someone younger or they are jealous of someone who is with someone much younger and they have no chance to be.
