brother muhammmad got married to a widow at the age of 24 and remained with her untill her death i.e when mohammed was 50 years,. All the marriages prohet did was after the age of 50, jst imagine why a person marries at this age when urge and the needs for having a women is no more. so what all the marriages he did was to bring peace to a warring tribes and all his wifes were widows except ayesha who was the daughter of his beloved friend. so a person is interested in marrying would have married many during the peak time of age i.e between 24-50 and not after 50. i better suggest you to read islamic books rather than remaining indark
