I was about to say something similar Aveline.
Another thought, if men are quickly remarrying and women are not, who are the women they are marrying?
I don't know any more than you do, but I would hazard a guess that the women who these widowers marry are either widows or divorcées of long standing, who are tired of being alone.
They could, of course, at least some of them could be women who for one reason or another had not married earlier in life and now felt ready to take the plunge.
It may well be that many of the relationships formed after the death of a spouse are more a matter of companionship than romance.
Widowers in their seventies and eighties probably no little or nothing about some or all of the tasks traditionally assigned to women, but if we are to be honest, do we women of the same ages necessarily know very much about the household repairs that have traditionally be a man's contribution to the household work?
