yes, why not.
i perfectly agree that a woman can mary a younger man, not only 1 year younger, but in my eyes...age is no creteria for love. the things which matter the most are your understanding and feasibility with the person.
so till u are comfortable with the person and think that you can smoothly lead a healthy life, then go for it.
the only problem i see in marring a younger man, is that in this scenario the female will be more mature then the counter part. and due to immaturity of male partner, some personl problems may arise.
