The time and place to bare your soul, if you must, is at the interview. Tout your achievements without embarrassing yourself. Let your accomplishments speak for themselves. To convey energy and stamina, mention your recent walking tour of the Hebrides. Tell the truth.
Nobody likes to be deceived.
If you're 93 years old, at least give a hint that you recall the Hoover administration. It's fine to be a free spirit and have controversial views, but again, if such issues must be discussed, do it in a personal setting, face to face. And you're under no obligation to tell anyone what organizations you belong to, where you get your hair cut or other information you consider personal. Don't try this at home. Don't know the tricks of the trade.
