An older man having dinner with his younger male business associate, no problem. If being a young women makes you "locked out" (due to social stigma on behalf of either party), it puts you at a perpetual disadvantage.

Due to the majority of gray hairs in industry being men, and the majority of current college graduates being women -- these type of quiet, almost polite disadvantages are worth talking about.
