An overwhelming number of people who choose to enter the dating world after age 50 have already lived at least 50 years. And, if they are like most people over 50 (and many people under) some of their early choices in life, while not resulting in life in a maximum security prison, may have still been in the category of 'Actions I Took Which May Have Been Beneath My Highest Possibility.'
We're the generation that changed the politico-socio-sexual attitudes of the entire free world in the sixties, so smoothing out our dating behavior would seem easy in comparison. Finger pointing won't help because we're all flawed. Dating isn't supposed to be a contact sport, and being able to see the unique person beyond their imperfections only requires a mirror.
