It is feminine to know about all hairstyles. Let's face it most all of us have been to a female hairstylist before. It is good to be in the loop of things if you have a son especially.
It is subjective to declare any US president as the "greatest leader of all time." Different presidents bring different strengths and accomplishments to the table, and their effectiveness as leaders is often a matter of personal opinion and ideological perspective. Additionally, historical context and long-term impacts also play a role in assessing a president's leadership.
