Are a 14.5-year age difference and a 15 cm height difference sufficient reasons to reject a well-mannered, educated, and professional doctor, even if there are others closer in age?

If a young man proposing to you is of good religious character and morals, he should not be rejected due to a difference in age or height, as these are not legitimate impediments in Sharia. A person of good religious character and morals is keen on honoring his wife. However, if there is no desire to marry him, or if there is a fear that the marital relationship would not last, there is no harm in waiting for another suitor, while prioritizing religious commitment and not exaggerating the importance of other desired qualities.
