Myth: With age you become set in your ways/stubborn.
Fact: As much as you would love to believe this, your personality remains pretty much the same as when you were in your middle age.
The point is, if you have been overtly stubborn to have your way all through your life, you will continue doing so in your older life as well. On the other hand, if you have been gregarious around people and attentive to others needs, as much as you cater to your own, chances are that you will continue doing so even in your later years.
