I knew both my grandfathers and one great grandfather, who made it to 101. One grandfather believed a shot of whiskey before bed was good for a child who was sick. My parents disagreed. My great grandfather drank wine all day and kept a low wage, low stress job. Claimed it was the secret to his longevity. My other grandfather drank his way through the depression and remained unemployed most of his life. He's the reason my father worked his ass off and gave me a strong work ethic.
