Manoah was born poor, sometimes had to go to bed hungry, but he made it to the MLB, got his fame and even a Cy Young contender. However, eventuality that hungry feeling and desire for food from the childhood kicked in to make him indulge in gourmet food, especially the lobster dinner, because he can afford any type of food under the sun now/ Sadly, it eventually made him overweighted to lose all his pitching skills.
The same can be applied to Kirk.
