Thank you, Bill, for this enlightening article. I do try learning something new whether daily, weekly--it's ongoing curiosity that keeps us informed and learning how we're changing and growing--even for a woman in the Third Third of my life! I'm sorry about your wife's death. Death will change us and is a wake-up call. My 36 year old son died almost 7 years ago. He inspires me always to question myself. Keep up your motivating writing.
