In the book Tuck Everlasting, Angus Tuck is the one who feels that being able to live forever is a bad thing. Emotionally he feels like he responsibility of living forever is a sad existence. Angus is the father of the group. Tuck is cheerful and boisterous. He greets Winnie in a positive manner.
There is no real description of his physical appearance that I could find in the book. We know he is married to Mae and they have two sons, Miles and Jessie. Miles had been married with children. I believe that Angus maybe around 40ish. He wears old fashioned clothing even years later when he goes back to Treegap.
