in the real world, there are no inherent legal restrictions or barriers preventing someone from marrying a partner who is older than them. People can choose to marry someone who is older, younger, or the same age as them, depending on their personal preferences and the laws of their country.
In many cultures and societies, marrying someone older or younger is quite common and widely accepted. The most important factor in any relationship is mutual love, respect, and compatibility rather than age differences.
That being said, societal attitudes towards age differences in relationships can vary, and individuals may face some social scrutiny or judgment. However, as long as the relationship is based on love and consent, it is entirely up to the individuals involved to decide what is best for them. Ultimately, age should not be the sole determining factor in deciding whether to marry someone or not.
